Io e la mia ragazza abbiamo passato il fine settimana in uno degli appartamenti di Azulis Terme Suites e siamo rimasti davvero colpiti. Moderno, curato e di una pulizia che non si trova spesso. L'appartamento era pronto all'uso, con tutto il necessario: dalle attrezzature per cucinare ai teli mare con gli ombrelloni. La cosa che ci ha fatto più piacere è stato trovare un piccolo regalo di benvenuto, vino con salame e formaggio, una cortesia che di solito da altre parti si paga. Lo consigliamo a tutti. Noi ci torniamo volentieri.
Het was een fantastisch appartement boven mijn verwachtingen!! Alles zag er top uit en de begeleiding was ook super duidelijk!! Ik ga hier zeker terug komen. Zo'n mooi appartement heb ik niet veel vaker gezien!!
We hebben hier 3 nachten geslapen. Ruime woonkamer, grote slaapkamer. Mooie entree. Alles duidelijk aangegeven. Toen we aankwamen mooie fles wijn. In de koelkast leuke verrassing: plaatselijke worst en kaas. Voldoende water. Communicatie erg vriendelijk en duidelijk. Ze hebben een fijn welkom gevoel gegeven. Zeker een aanrader.
A modern yet chic apartment, strategically located just outside Olbia's old town. The views are fantastic, and every detail has been thoughtfully designed with guests' comfort in mind. Our hosts were incredibly attentive and always available to help. I truly loved my stay and hope to return someday. Highly recommended!
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. The villa itself is high-end in every sense, with real attention to detail in the design. Traveling with our baby, we were especially grateful for the pool, and the rooftop quickly became our favorite spot to wind down and watch the sunset. Highly recommend, especially for families looking for something special.
Che soggiorno meraviglioso a Villa Aramis, a Golfo Aranci! La villa è semplicemente splendida: design curato, spazi ampi e comodi, materassi di ottima qualità su cui si dorme benissimo, e una vista mare che lascia a bocca aperta. Tutto pulitissimo fin dall'arrivo, una cura da vero hotel di lusso. La cosa che fa la differenza è che AZULIS è gestita direttamente dai proprietari: il team di RENTAL12 è stato gentile, attento e sempre disponibile. Onestamente 5 stelle sono poche per un posto così. Noi non vediamo l'ora di tornare!
Paikka oli super siisti, sijainti mahtava, tuntui aivan luksukselta. Koko perhettä harmitti kun ehdimme olla vain yön sijainnissa. Talo tarjosi viini, juustoa, leikkeleitä. Ulkosuihku ja iso patio kruunasi kesä helteet. Selkeät ja helpot ohjeet perille. Jos menemme Olbiaan uusiksi, varmasti majoitumme täällä.
Such a great place. So clean, beds comfortable, 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.
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 was the private pool, but the real magic is the panoramic sea views from the rooftop terrace, especially at sunset. Everything felt very personal and well managed — it's an owner-operated property and you can really tell there's care behind every detail. Communication was smooth throughout, and direct booking made everything stress-free. Would absolutely come back again.
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! Breathtaking sea views and beautifully refined, design-led architecture by Anastasia Duke (I asked who made it so lovely!). Every space feels elegant, luxurious, and thoughtfully designed. What stood out most was the hotel-level cleanliness — immaculate on arrival. AZULIS being owner-operated is clearly reflected in the quality of service. Truly a gem!
We absolutely LOVED staying at this flat in Olbia — it genuinely made our honeymoon feel even more magical. We arrived from JFK at 10AM and they let us check in that early! Inside, we were welcomed with a chilled bottle of sparkling wine and a free Sardinia tote bag. The flat itself was absolutely spotless and beautifully maintained, and the secure gated parking was a huge relief. We'd go back in a heartbeat. Grazie Mille Floriana & Kristina!
Definitely deserved maximum rating! Premium standard, professional care of the customer. Such a pleasure to be your guest. A sincere recommendation to everyone!

Perfekt durchdachte, hochwertige Ausstattung, schönes Design. Immer schnell erreichbare Gastgeber, sehr freundlich und hilfsbereit. Bester Service. Die Lage ist optimal, mitten im Leben Olbias.
Très belle expérience Airbnb! Le logement était fidèle aux photos. Tout était très propre et parfaitement équipé. Le quartier est calme. L'équipe, Floriana et Kristina, ont été super réactives, aimables et serviables. Notre arrivée et notre départ se sont très bien passés. Les instructions étaient simples et claires. Nous reviendrons très vite.
Prachtig, nieuw appartement. Van alle gemakken voorzien. Een absolute aanrader!
L'appartement correspondait parfaitement à la description. Très bien équipé et très bien situé. Nous avons passé un très bon séjour!
Très bon accueil et réactivité des propriétaires. Appartement tout confort, propre et moderne, en plein cœur de la vieille ville d'Olbia. Les attentions à l'arrivée font la différence.
Nous recommandons vivement Floriana, très disponible et arrangeante. Nous avons pu accéder au logement plus tôt que prévu, et de petites attentions nous attendaient à notre arrivée. L'équipe a même fait venir le ménage après 20h pour nous apporter des draps supplémentaires. Les guides et vidéos mis à disposition ont été très utiles.
Calore, comfort e cura in ogni dettaglio. Un soggiorno semplicemente meraviglioso. L'appartamento suite accoglie con un'atmosfera calda e naturale, fa sentire subito a casa: luci e dettagli curati e un senso di autentico. Tutto è impeccabile, pulito, ordinato e preparato con grande attenzione.
Superb Sardinia stay. 5 star experience. AZULIS is comfy, modern and very well maintained. Away from the maddening crowd. Thank you for our wonderful stay, we will be back!
Wonderful stay in Olbia! We absolutely loved our stay at this apartment. The place was spotless. Check-in was smooth and stress-free. The property manager was responsive and very helpful. A fantastic place to stay in Olbia. Great value for money — highly recommended!
Great choice for a comfortable stay. The apartment has a modern and clean design with a comfortable and spacious layout. It is bright and well furnished, and the location is great. Highly recommended — I would stay there again without any hassle.
Truly one of the best stays we have had. The townhouse is spacious, spotless and beautifully renovated, with everything thought through for an effortless holiday. Location is perfect for cafés and the promenade. Parking was easy and hosts were super responsive. We would happily return.
Exceptional apartment in a calm street of the old town. Immaculately clean, stylish and very functional with a proper kitchen. Digital check-in was smooth and the team replied instantly. Great base to explore Pittulongu and Bados. We loved the beach kit and thoughtful touches.
Beautiful penthouse with lift, a big terrace and a wonderful view over the centre. Everything felt new and premium. Parking on site made it easy for day trips. Short walk to Corso Umberto. We would book again for a longer stay next time.
Everything was impeccable. The townhouse is generous in size, beautifully finished and spotless. Location is perfect for the historic centre. Communication was quick and helpful with excellent local tips for beaches and restaurants.
Perfect location in the historic centre yet peaceful at night. The apartment felt brand new and very thoughtfully equipped. Hosts were kind and fast to help. We appreciated the detailed guidebook and beach towels.

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 1,550+ 5 star reviews since 2021.
RENTAL12 reviews are 100% verified-stay only. Sourced from Airbnb (852), Booking.com (386), Google (515), Tripadvisor (25), Trustmary (162 direct) and an independent 3rd-party consumer-protection aggregator (93) — every review is tied to a paid reservation and reconciled monthly. Aggregate: 4.9 of 5 from 1,550+ 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 1,550+ 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) and an independent 3rd-party consumer-protection aggregator. This page links directly to each. Last verified 29 June 2026 with 2,033 total reviews combined across all sources (1,550+ rounded canon).
Trustmary syncs new platform reviews within hours of posting — its dashboard at trustmary.com/review/www.rental12.com is the single freshest source. The 12 most recent reviews on this page are all from the last 30 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.
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.
