Every one of the 37 owned-and-operated RENTAL12 and AZULIS apartments in Olbia and Golfo Aranci runs the same 70-point cleaning checklist between stays, backed by a 24/7 maintenance SLA. Housekeeping is in-house, never subcontracted: fresh linen and towels for every guest and a final on-site inspection before key handover. Owner-operated since 2021 — Floriana Panvini Rosati and Kristina lead the Olbia team directly, with no outsourced call centre.
"Quality is non-negotiable. Every one of our 37 apartments runs the same 70-point cleaning check and the same 24/7 maintenance SLA."
— Kristina Zotova, Co-Founder & COO, RENTAL12
Rated 4.9 across 2,000+ 5 star reviews, with new five-star reviews added weekly.
"Every review you read here was written by someone who slept in one of our beds. We do not buy reviews, we do not write reviews, and we do not hide the bad ones. The 4.9 number is built one stay at a time."
"Cleanliness scores stay at 4.9 because we treat every turnover like a hotel turnover, not a holiday-rental quick wipe. Same checklist, every property, every guest."
"Every review on this page maps to an entry in our reservation ledger. Names, dates, properties, payment receipts — all reconciled monthly. We publish the reviews because we are willing to publish what is behind them: a paid booking from a real guest. That is what 'verified' should mean."

We had a wonderful stay at Floriana and Kristina’s place. The apartment was very comfortable, clean, and well maintained. Check-in was easy, the instructions were clear, and the communication and service were excellent — 10/10.
Our stay at the villa was absolutely wonderful and honestly exceeded our expectations. From the moment we arrived, everything felt special.
We had a wonderful stay! Floriana and Kristina were always very quick to respond and often checked up to make sure everything was going well. They even had a little welcome gift waiting for us.
We had a fantastic stay and would highly recommend this apartment. The location is perfect – right in the heart of the city, yet tucked away in a quiet side street.
Perfectly clean, central house. Beautifully renovated and very nicely air-conditioned. Lovely furniture and well equiped (kitchen, wardrobes, bed and cushions, etc) Floriana and Kristina were very reactive but people should be aware that…
Such a great place. So clean, beds comfertable, all amenities that we needed— loved the washer/dryer— great air conditioning —and so close to downtown with great restaurants. Perfect place for a family to explore the area.
Ottima posizione e pulizia eccellente. Mi sono trovato molto bene con il check-in a distanza, sono arrivato a notte tarda e in altre strutture, in situazioni simili, ho dovuto aspettare l'host, mentre qui è stato tutto super veloce e…
Although I was hesitant about providing my passports, Floriana was very patient, helpful and reassuring. She was responsive for any questions and offered a lot of support.
Had such a great stay here! Everything was amazing. They let us do early check-in AND late check-out, which honestly made the whole trip so much less stressful.
We really enjoyed our stay at Floriana and Kristina' s place. The place was spacious, clean and modern. The location was in a beautiful neighbourhood and close to shops and cafes. The hosts were friendly . Thanks Mohammed
We had an absolute 10/10 stay in the heart of Olbia! To be honest, the level of hospitality and professionalism we received from dear Floriana and Kristina was truly beyond what I have seen in many 5-star hotels.
We stayed for 4 nights and felt very comfortable. The place looked exactly like the pictures. Everything was clean and had everything you needed. Location was great, it was walkable to the parking lot, restaurants, and shops.
Great, clean renovated place. Right in the middle of everything. We paid for the parking lot and it was very convenient to come out of the apartment, walk a short block and a half and get to the car.
My family absolutely loved our stay in this apartment. It was impeccably clean, and beautifully modern, with thoughtfully designed interiors and luxury hotel–like amenities.
Its hard to find a property that is even nicer than what the pictures and description state. Highly recommended the Golfo Aranci properties, they are pristine, high tech and incredibly modern.
Villa Aramis a Golfo Aranci, che dire. Bella nelle foto, ancora più bella dal vivo. Tutto curatissimo, materassi top, pulizia impeccabile e una vista mare dalla terrazza che non ti stanchi mai di guardare.
This was one of the best Airbnbs I have ever stayed in. Floriana and her team were amazing and very communicative throughout the whole process. The airbnb was very clean, modern, and in the middle of the city center.
Amazing apartment in the city with private parking. Super modern and new - fully equipped kitchen, beach amenities. A perfect stay, I fully recommend. Well thought through light concept, nice balcony, quiet and safe neighborhood.
Floriana ist eine hervorragende Gastgeberin! Das sie das nicht erst seit gestern macht, ist offensichtlich! Das war neben der Villa sicher das BESTE!
I don’t even know where to start. Firstly - the apartment looked just like on the photos and we immediately felt at home. The flat had a very cozy feeling to it which is actually something you can’t see on the photos.
Chosen for what they actually say about the apartments, the cleaning and the team. Longer reviews are shortened at a sentence break; the link opens the full text on the platform.
This is the second property we have stayed in managed by Floriana and Kristina and the second time did not disappoint. Their properties are beyond what you expect from an Airbnb. The attention to detail is incredible. From the furniture to the lighting to the TVs to the linens to the wine and cheese gift, everything is high end. The spaces are very modern and well thought out.
A Five Star review for a Five Star property. Sparkling clean and new, moderne, attractive, just as described. So much to do in this central vicinity, tons of great restaurants, bars, gelato shops, people watching and just being in the center of things. Having a car was especially easy as parking within yards of property. 15-20 minutes drive to numerous postcard beaches/coves.
Our stay at the villa was truly unforgettable and exceeded all our expectations. The villa is beautiful, spacious, immaculate, and even better than the photos. The amazing pool was one of the absolute highlights. We spent so much time there as a family and loved every moment. The location is also unbeatable, with the beautiful beach just a 3 minute walk away.
Floriana, Kristina and the Rental12 team were amazing. My girlfriend and I stayed here for a week. The apartment was beautiful and way more thoughtfully equipped than most places I’ve stayed (e.g. cooler, beach umbrella, beach towels and even ice packs.) The bathroom was a highlight too with great water pressure, plenty of hot water, and heated floors.
It took us 8 minutes to get to Floriana and Kristina's place from the airport. We had taken an evening flight so it was great to only have to drive a short distance to our accommodations. But what was amazing was the selection of restaurants, shops and live music available once we got settled in.
This was the best Airbnb apartment we’ve stayed in. The entire building is newly built, modern, and exceptionally clean — from the entrance and hallways to the elevator and the apartment itself. Since we were traveling by car, we especially appreciated the secure parking area with a designated space and an automated gated entrance.
My family had an incredible stay at this property…probably the best Airbnb we have stayed at! Floriana and Kristina were extremely welcoming and helpful. Instructions were very clear, they gave helpful information about the property and the area (including a great blog with recommendations) and they were in communication with me throughout our stay.
My family and I have stayed at several properties using AirBnb and this place was remarkably the cleanest. The location was excellent. Very close to Olbia Airport, lots of amenities nearby (within five minutes walking distance), the parking lot made life very easy, and I have rarely come across such responsive hosts.
🌟🌟🌟🌟🌟 Schöne Wohnung in PERFEKTER LAGE. Direkt am Zentrum, gut erreichbar mit öffentlichen Verkehrsmitteln und dennoch ruhig gelegen. Strand mit dem Bus in 30Minuten erreichbar. Die Anbindung an den öffentlichen Verkehr ist sehr einfach. Für nur 1€ fährt man 90Minuten mit dem Bus, einfach per App (ASPO) zu buchen, Haltestelle 200m entfernt.
Ein absoluter Traumurlaub auf Sardinien! Unsere Reise war einfach wundervoll, was wir zu einem großen Teil dieser fantastischen Unterkunft zu verdanken haben. Die Lage ist perfekt: absolut zentral, aber dank der ZTL (verkehrsberuhigte Zone) ab 17 Uhr abends herrlich ruhig.
Wir haben uns sehr wohl gefühlt, es war wie in der Beschreibung. Sehr sauber und modern war die Wohnung, die Austattung war perfekt, es fehlte an nichts. Sogar für den Strandtag gab es Strandmatten, Kühltasche, Kühlakkus, Strandtasche und einen Sonnenschirm. Praktisch war auch die Waschmaschine in der Wohnung.
Villa Aramis ha superato ogni aspettativa! Appena entrati siamo rimasti senza parole: tutto pulitissimo, curato nei minimi dettagli e ancora più bello dal vivo che nelle foto. Gli spazi sono ampi e comodi, pensati davvero per rilassarsi, e i letti sono comodissimi , abbiamo dormito benissimo ogni notte.
Miglior esperienza di sempre! Villa stupenda, con un design curato nei minimi dettagli: minimalista ma di grande impatto. Le foto ci avevano già conquistato prima della prenotazione, ma all’arrivo c’è un effetto WOW che lascia senza parole.
Nous avons passé 7 nuits début septembre 2025 dans ce logement en parfait état, très bien équipé, super propre et agréable, dans une maison rénovée, très bien située et calme via Cavour dans l’hyper centre de la vieille ville d’Olbia, avec des hôtes très réactives.
Excelente experiencia de ppio a fin. Desde antes de llegar, Floriana y Kristina estuvieron pendientes de todo. Nos recibieron con amabilidad y siempre estuvieron disponibles por si surgía cualquier inconveniente, haciéndonos sentir acompañados durante toda la estadía. El dpto es impecable: ubicación es excelente, limpieza perfecta y equipado con absolutamente todo.
To był wspaniały pobyt u Floriana i Kristina. Apartament jest bardzo wygodny i jest w nim wszystko aby wspaniale wypocząć. Jest bardzo czysty i przestronny. Kontakt z Floriana i Kristina przebiegał bez zarzutu, był proaktywny z ich strony.
I had an exceptional stay at AZULIS Villa Athos in Golfo Aranci, Sardinia. It’s easily one of the finest private villa rentals I’ve experienced so far! Located in northern Sardinia, the villa offers breathtaking sea views and beautifully refined, design-led architecture by Anastasia Duke (I asked who made it so lovely!).
We spent a week at this villa in Sardinia and it genuinely exceeded our expectations. From the moment we arrived, the service was spectacular. The team was incredibly responsive, and anytime something needed attention they came and fixed it right away, no fuss. That kind of attentiveness made the whole stay feel effortless.
We stayed at this Golfo Aranci villa and honestly it exceeded expectations in every way. The property is brand new and feels very private, peaceful, and incredibly well designed. The highlight for us was definitely the private pool, which was perfect for relaxing during the day, but the real magic is the panoramic sea views from the rooftop terrace, especially at sunset.
Amazing stay from A to Z!!! We rented the AZULIS 2 apartment and we absolutely loved it, it was perfect! It was super clean, everything was brand new, very technological (no physical key, the access to the building and the apartment were done by an app on your phone) and it was super well equiped.
Wir (2 Erwachsene und 1Teenager) verbrachten 1 Woche im Appartement Azulis nr.3. Es war hervorragend und wir haben es sehr genossen. Das Appartement ist neu, gepflegt, stilvoll eingerichtet, mit allem üblichem Komfort und sehr sauber. Die Küche ist gut ausgestattet - inkl. Spülmittel, Geschirrtüchern, Geschirrspültabs, Mistäcke sind ausreichend vorhanden.
Jesteśmy rodziną z 3 malutkich dzieci, która właśnie spędziła w Apartamencie AZULIS nr 2 23 dni. Jak się okazało byliśmy w nim pierwszymi gośćmi ;) długo szukaliśmy noclegów na Sardynii, bo nic nam się nie podobało albo cena była astronomiczna, aż wreszcie zobaczyliśmy apartament Azulis i to był strzał w 10 :) gdzie cena odpowiadała jakości, a jakość cenie.
⭐️⭐️⭐️⭐️⭐️ Lusso e relax a Olbia Abbiamo appena trascorso un soggiorno indimenticabile ad Azulis, a Olbia, in tre persone. L’appartamento è un vero gioiello: curato in ogni minimo dettaglio, elegantemente arredato, moderno ma con un’anima accogliente.
Garibaldi Studio è stata una scelta davvero azzeccata per il nostro soggiorno. La posizione è perfetta, in pieno centro, con ristoranti, negozi e il lungomare raggiungibili comodamente a piedi, ma allo stesso tempo l'ambiente è tranquillo e molto riservato.
If you’re looking for a clean, professional and quiet stay in the heart of Olbia, look no further. This is my second time staying with “Number 12” properties, and they’ve outdone themselves again. Everything from check-in to during your stay assistance and recommendations is managed wonderfully.
We absolutely loved our stay at this beautifully restored apartment in the heart of Olbia. The location was perfect, and Floriana and Kristina were fantastic, so helpful and great at keeping us informed before and during our stay.
5+ out of 5 stars. This was an outstanding property. It was very tastefully furnished in an excellent location, close to shops and restaurants, secure parking was included, and the attention to detail was remarkable—including wash clothes, insect repellent, beach towels, and even a cooler bag and umbrellas for the beach. We would definitely stay here again.
This cottage was the prefect place for my family of 3! It was super clean, comfortable and modern. There is nothing like coming back from a hot day exploring Sardinia and having an AC that works great! Also the washing machine helped out a lot. The host Kristina was so kind and generous. Response time to messages was amazing.
Excellent accommodation. Everything is ultra-modern, beautiful, clean, and high-quality. The apartment is very well-equipped; you'll find everything in it, including a washing machine. Comfortable beds, plenty of towels. Excellent service and information from the hosts before and during the stay.
Everything is perfect in this apartment. It is obvious that the owners put their soul into it. There is everything you need, as well as very soft towels, a high-quality orthopedic mattress, air conditioning, a soft carpet on the floor, a coffee machine. Convenient location, everything is within walking distance.
One of the best apartments I’ve ever stayed in – and I travel quite often! The host has thought of every single detail, and the attention to detail is truly impressive. Everything has been designed and prepared with great care. The apartment is beautifully finished, with high-quality furnishings and equipment throughout.
To najpiękniejszy apartament jaki kiedykolwiek wynajmowałam. Jest w nim absolutnie wszystko! Nowoczesność i czystość na światowym poziomie, wyposażenie aż zaskakująco bogate! Lokalizacja bardzo dobra i bezpieczna. Kontakt z wynajmującym doskonały! Bardzo polecam, chętnie tutaj wrócę. Aż trudno uwierzyć że w tak dostępnej cenie może być taki doskonały nocleg ❤️
Contemporary and elegant apartment designed with great taste and practicality. Every single detail is thought of to make your stay as comfortable as possible. The kitchen and bathroom have all the necessities with modern and useful items. The bedroom is comfortable and spacious.
This lovely property was perfectly placed for the old town of Olbia close to wine bars and restaurants. Spotlessly clean and everything in good working order. Absolutely faultless.
The property is new and beautifully spacious, with a kitchen fully stocked with everything you might need to cook and feel at home. There’s a big TV in every room, and the hosts even thought of the little but important details like extra towels, beach equipment and special beach towels.
Struttura completamente nuova e con arredi di lusso, centralissima ma in una via tranquilla. Parcheggio comodo e vicino. Appartamento ricco di ogni servizio, dalla cucina agli asciugamani è tutto nuovo e funzionale. Floriana è stata eccezionale e ci ha guidati in questa esperienza che porteremo sempre con noi. La consiglio assolutamente!!
Abbiamo soggiornato dal 25 al 28 aprile negli appartamenti Tigellio per alcuni giorni e l’esperienza è stata davvero eccellente. L’appartamento è moderno, curato in ogni dettaglio, estremamente pulito e dotato di tutto ciò che serve per sentirsi subito a casa.La posizione è comodissima, ideale sia per raggiungere il centro di Olbia sia per esplorare le spiagge della Costa…
We absolutely loved our stay at this apartment in Olbia. The place was spotless. Check in was smooth and stress-free. The property manager was responsive and very helpful. It’s a fantastic place to stay in Olbia. Great value for money - highly recommended!
家族でオルビアを訪れ、Azulisアパートメントに滞在しました。部屋に入った瞬間から、オーナーがどれだけ心を込めて準備してくださったかがひしひしと伝わってきました。細部までしっかり整えられており、その丁寧さに本当に感心しました。日本人として、清潔さはとても大切なポイントです。海外旅行では衛生面で不安を感じることもありますが、こちらのアパートメントは隅々まで清潔に保たれており、家族全員が安心してリラックスして過ごすことができました。他の方の体験談を耳にすることもある中で、こうした宿に出会えたことはとても嬉しかったです。オルビアを訪れる際には、ぜひAzulisアパートメントをおすすめしたいと思います。また訪れる機会があれば、迷わずこちらを選びます。素晴らしい滞在をありがとうございました。
My wife & I recently had the pleasure of staying in a charming small apartment in the heart of Olbia, and I can't recommend it highly enough! From the moment we first made contact, the service was exceptional. The hosts went above and beyond to ensure our stay was nothing short of amazing.
We do not gate any review behind our own moderation. Every count and rating below links to the live source profile — read everything yourself.
Quick answer: Every review on this page is verified — sourced from Airbnb, Booking.com, Google, Tripadvisor, Trustmary — and tied to a paid stay reconciled monthly against the RENTAL12 reservation ledger. 4.9★ aggregate from 2,000+ 5 star reviews since 2021.
RENTAL12 reviews are 100% verified-stay only. Sourced from Airbnb (1,015), Booking.com (473), Google (494), Tripadvisor (27), Trustmary (172 direct) — every review is tied to a paid reservation and reconciled monthly. Aggregate: 4.9 of 5 from 2,000+ 5 star reviews since 2021.
Only platforms that require a completed paid stay before posting are sourced (Airbnb, Booking.com, Google, Tripadvisor). Trustmary independently aggregates them at trustmary.com/review/www.rental12.com — the public audit anchor.
RENTAL12 maintains a 4.9 of 5 (≈ 9.8 of 10) aggregate from 2,000+ 5 star reviews across 37 owned-and-operated properties and 6 verified sources since 2021. No active property is rated below 4.7. Property-by-property variance sits at ±0.1 around the 4.9 mean.
Multi-night-average and post-stay-survey scores are tracked internally but not published — the public 4.9 is the conservative figure. Updated each Trustmary sync (typically within hours of a new platform review).
Cleanliness is the highest-rated aspect on every platform — typically 4.95+ on Airbnb's 6-criterion scoring. Reviews consistently mention 'spotless', 'immaculate', 'hotel-grade' preparation, fresh linens and the AZULIS-standard cleaning protocol that runs after every guest, on every turnover.
Hotel-style protocol: same checklist every turnover, fresh linen and towels every guest, deep-clean every quarter, final on-site inspection by Kristina or her team before key handover. Housekeeping is in-house, not subcontracted.
Reviews come exclusively from third-party platforms that require a completed paid stay before posting (Airbnb, Booking.com, Google, Tripadvisor). RENTAL12 cross-checks names, dates and properties against the internal reservation ledger every month — the CFO (Simon) signs off. Zero fake reviews detected in audit history.
No fake review can be posted on these platforms without a paid reservation in the first place. Trustmary mismatches (duplicate reviews, name typos) are flagged with the aggregator. See our verification process for the full audit chain.
Yes — transparency is core. Public profiles on Airbnb, Booking.com, Google and Tripadvisor display the full spectrum of ratings. Constructive feedback (street-noise on weekend nights, historic-centre stair access) is preserved unchanged and used to inform future renovations and pre-booking property descriptions.
Examples kept on platform: Markus mentions weekend street noise; Ruth notes 'rather dark apartment'. Where issues are structural (e.g. historic-centre stairs), the property description includes a clear pre-booking warning.
The same core reviews appear on OTAs and on this hub. Because RENTAL12 is owner-operated by Lion Development S.r.l. — same legal entity that owns the buildings and signs the booking — guests highlight more personal communication, better-maintained properties and consistent 4.9 quality across all 37 units.
Multi-host OTA agencies typically average 4.4–4.6 because they manage third-party inventory inconsistently. RENTAL12's 4.9 reflects vertical integration: same owner, same renovation standard, same housekeeping team, same guest-communication SOP across every unit.
Many guests name Floriana and Kristina (RENTAL12 co-founders) directly and praise fast, human communication on WhatsApp, email and OTA messaging. Reviews describe clear pre-arrival instructions, smooth digital check-in via Vikey, and helpful local tips — same experience direct on rental12.com or through any platform.
Direct guests on rental12.com pay no service-fee markup vs the OTA price. Average WhatsApp response time during business hours is under 10 minutes per the internal CRM. Karim, Anne-marie, Guillaume, Aisling all named the team directly in their reviews.
Feedback is logged in the internal CRM and reviewed in monthly ops meetings. Repeated suggestions trigger changes — bedding upgrades, new appliances, revised check-in instructions, refined cleaning routines. This continuous loop is the reason cleanliness and comfort scores have stayed at 4.9+ since 2021.
2024–2026 examples: smart-TV upgrade portfolio-wide; expanded family kit (cot, highchair, bottle warmer); earplugs in historic-centre flats after weekend-noise reviews; beach kit (umbrella, towels, bag) standardised across all summer-active units.
The freshest reviews are on the live platform profiles: Airbnb (rental12 host), Booking.com, Google Maps, Tripadvisor (AZULIS Apartments), Trustmary (aggregator). This page links directly to each. Last verified 15 September 2026 with 2,181 total reviews combined across all sources.
Trustmary syncs new platform reviews within hours of posting — its dashboard at trustmary.com/review/www.rental12.com is the single freshest source. The 20 most recent reviews on this page are all from the last 90 days.
Three themes recur in 80%+ of 5-star reviews: (1) cleanliness — 'spotless', 'immaculate', 'hotel-grade'; (2) design — AZULIS interiors, modern finishes, hand-curated original art by Anastasia Duke; (3) hospitality — Floriana and Kristina's WhatsApp responsiveness and local insider tips.
Recurring secondary praise: dedicated parking inside Olbia's ZTL via Via Sassari 20; baby-friendly kit (cot, highchair, bottle warmer); detailed digital guidebook with restaurant and beach recommendations; flexible early check-in / late check-out when occupancy permits.
Yes — every one of the 37 RENTAL12 apartments runs the same 70-point cleaning checklist between stays; the aggregate rating is 4.9 of 5, with new five-star reviews added weekly.
Housekeeping is in-house, never subcontracted: the same 70-point checklist runs on every turnover, fresh linen and towels go out for every guest, and Kristina or her team inspects on site before key handover. A 24/7 maintenance SLA backs every stay.
Your honest feedback — good or bad — keeps the 4.9★ honest. Two minutes is all it takes, and your name and stay date are matched against our reservation ledger before publication.
