"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."

All amenities, fully equipped apartment. The owners care about your comfort including beach umbrella, beach towels and beach bag. Rather dark apartment.
Een erg mooi appartement op een super locatie! Een erg vriendelijke host. We hebben de parkeerplaatsen bij gehuurd wat erg fijn was. Zeker een aanrader als je naar Olbia gaat!
Good communication with owners, well situated and met all our needs.
Dobro i promišljeno opremljen. Nedostaje barem minimalni vanjski prostor.
Świetne miejsce, apartament w pełni wyposażony, nowoczesny, idealna lokalizacja.
La struttura è nuova, dotata di ogni confort e pensata per tutte le esigenze. Appartamento rifornito benissimo: borsa frigo, ghiaccio, ombrello, ventilatore, shampoo, bagnoschiuma, lavasciuga. Letto comodo. Comodissimo parcheggio chiuso.
Great location, parking and hosts! And lots to make it baby friendly including a bottle warmer, cot, nappy bin, highchair etc! Brilliant.
There was nothing more we could have asked for. The property owners have thought of every little detail to make the stay as comfortable and pleasant as possible. The beds are super comfortable, even the sofa bed. There is even beach equipment provided and large smart TVs in all rooms. Earplugs are provided so the central location is not a problem.
Our stay at Fontana Suite was absolutely exceptional, everything was simply perfect! The apartment is beautiful, impeccably maintained, and feels brand new. It is fully equipped with absolutely everything you could possibly need. A special thank you goes to the amazing hosts, Kristina and Floriana, who were truly outstanding, warm, attentive, and incredibly professional.
An exceptional stay at AZULIS Highest Luxe Apt 1. The apartment is absolutely stunning, beautifully designed, immaculately clean, and finished to a truly luxurious standard. It goes far beyond the extras you would normally expect, with every detail thoughtfully considered. The peaceful garden and spacious setting add to the sense of relaxation. The hosts were extremely kind, attentive, and very helpful. A truly special place.
Lage und Parkplatz. Konnten früher rein und später raus. Am Wochenende ist es in den Straßen doch recht belebt, kann bei Kindern schwierig sein, wenn sie schlafen sollen.
Zelo dobra stvar z aplikacijo za odpiranje vhodnih vrat. Dobili veliko dodatne opreme — brisače za na plažo, senčnik, hladilno torbo. Lokacija je super.

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 or Trustpilot (RENTAL12 + AZULIS) — 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 (746), Booking.com (343), Google (197), Tripadvisor (24), Trustmary (157) and Trustpilot (102 — 73 RENTAL12 + 19 AZULIS + 10 Garibaldi 4 Suites) — 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 34 active properties and 6 platforms 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 34 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 Trustpilot (RENTAL12 + AZULIS). This page links directly to each. Last verified 16 May 2026 with 1,569 total reviews combined across all platforms (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.
