At RENTAL12, we believe true luxury begins with integrity. Every home we design in Sardinia is created with respect — for our guests, our island, and our people. We own every property, maintain every detail, and price every stay fairly from the start. No inflated rates, no fake promotions — just real value, genuine care, and transparent hospitality.
Our mission is simple: to host consciously. To protect Sardinia’s beauty, empower our team, and welcome every guest with sincerity, comfort, and heart.
At Rental12, we don’t just rent apartments — we create experiences you’ll remember.
With 15,000+ guests hosted and thousands of five-star reviews on Airbnb and Booking.com, we’re one of Sardinia’s most trusted boutique hosts. We are the
only owner-operator in Sardinia with 25+ personally owned & managed listings — including
designer apartments in Olbia,
refined houses in Olbia, and
exclusive villas in Golfo Aranci.
This model guarantees premium quality, meticulous maintenance, and genuine commitment in every stay. Our in-house team ensures every detail reflects high standards of design, comfort, and Sardinian charm.
Our mission is simple: earn your trust, deliver authentic island comfort, and help you fall in love with Sardinia — one unforgettable stay at a time.
Whether you’re visiting for a romantic weekend, a remote-work retreat, or a family beach holiday, Rental12 offers the perfect home base. Our portfolio spans cozy studios, two-bedroom designer suites, and spacious villas — each professionally styled, fully equipped, and located in Olbia, Pittulongu, Golfo Aranci, and (soon) La Spezia.
All properties include premium linens, air-conditioning, high-speed Wi-Fi, and a beach kit (towels + parasol). Your Sardinian welcome features curated local wine, pecorino, and sausage. 🧀🍷☀️
We never outsource quality. Our internal team handles deep cleaning (2–4 hours), linen service, maintenance, and guest support for consistency, reliability, and rapid response. We are proud to have no unresolved guest issues.
We’re not a marketplace. We own 100% of the properties we list. Every apartment and villa is hand-selected, custom-designed, and maintained to the standards we expect for ourselves. From CREO kitchens and designer lighting to secure Vikey smart access, everything is curated in-house.
We are not an agency — we are the owners. Your rental is never subject to third-party unpredictability. What you see is what you get — and then some.

Rental12.com is more than just a rental platform — it's a dedicated team of passionate professionals who work every day to create unforgettable guest experiences across Sardinia and beyond. From personalized guest care to spotless apartments and behind-the-scenes logistics, here’s who makes the magic happen.
Floriana is the driving force behind RENTAL12 and the founder of NR12 Exclusive Real Estate. A visionary entrepreneur with a deep love for Sardinia, Floriana combines hospitality, business strategy, and local knowledge to craft holiday experiences that are as smooth as they are soulful. She hand-picks every apartment, oversees guest communication, and ensures each stay reflects the high standards RENTAL12 is known for. Her passion? Turning every guest into a Sardinia lover for life.
Kristina is Floriana’s right hand and a key pillar of RENTAL12 success. As our in-house strategist and spreadsheet wizard, she oversees operations, analyzes booking data, and ensures nothing slips through the cracks. Kristina is also our lead graphical designer, keeping visuals, Pinterest boards, and branding perfectly on point. From apartment listings to guest logistics, she is the calm brain behind the daily brilliance — and a driving force for consistent quality across AZULIS residences.
Anastasia Duke is the creative mind behind the unique look and feel of many RENTAL12 spaces, including the AZULIS residences. With a modern yet organic design language, Anastasia elevates each property into a boutique-style retreat using custom furniture, tactile materials, and an eye for flow and light. Her design vision helps RENTAL12 apartments stand out across platforms — and in real life.
Alejandro ensures that every property runs like clockwork. From technical repairs to last-minute fixes, his hands-on approach and eye for perfection keep our apartments guest-ready at all times. Guests may never meet him — but they benefit from his meticulous work every day.
Nadiya is the silent engine powering Rental12’s guest services. She handles everything from guest registration and Vikey access systems to scheduling mid-stay cleanings and team coordination. Her calm professionalism ensures every check-in is seamless, every document complete, and every stay perfectly organized.
Diego oversees our on-site warehouse and laundry operations — an essential role that ensures every Rental12 apartment is stocked with fresh linens, beach towels, and extras like toilet paper and dishwasher tablets. He manages deliveries, linen cycles, and inventory so guests never run out of the essentials. Clean, crisp, and on time — that's Diego's daily mission.
We’re proud to work with a dedicated in-house cleaning team of six professionals who are the heartbeat of every stay. They clean thoroughly (2 to 4 hours per turnover), prepare fresh beds and towels, and create a welcoming feel in every space. Many guests mention the cleanliness of our apartments in reviews — and it's all thanks to them.
At Rental12.com, we believe luxury lies in the details. Whether it’s a handwritten welcome note, a perfectly ironed pillowcase, or a wine bottle chilled before your arrival, our team delivers service with heart. No automation can replace human attention — and that’s what we provide.
Whether you're booking for a night, a week, or a long-term remote work stay, we’re here to make sure everything flows smoothly. We handle the small things so you can enjoy the big moments in Olbia, Golfo Aranci, and across the Costa Smeralda.
Thank you for choosing Rental12.com.
From our team to your stay — we can’t wait to welcome you to Sardinia.
How is Rental12 different from an agency?
We are an owner-operator: we own and manage every listing. In-house teams handle cleaning, laundry, and maintenance for consistent quality and fast resolutions.
Who do I contact during my stay?
Our multilingual team is available daily. For operations, Alejandro coordinates maintenance and fixes; client relations are led by Floriana; overall operations and standards by Kristina.
Who designs the interiors at Rental12 and AZULIS?
Our design language is led by Anastasia Duke, ensuring each apartment or villa feels calm, elegant, and functional for short-stay living in Sardinia.

NR12 is the exclusive management platform behind Rental12.com — Sardinia’s trusted boutique, owner-run brand for design-forward vacation accommodations (apartments, villas, luxury suites) in Olbia, Golfo Aranci and the Costa Smeralda. Whether you’re staying one night or a full season, we deliver boutique-hotel consistency with the soul and space of a private home.
We set the benchmark in Northern Sardinia for short-term stays. Our in-house teams provide hotel-grade housekeeping, deep-clean linen service, rapid maintenance response, and personal guest care — fully integrated into your booking. No outsourcing. No surprises. Clean, beautiful, and perfectly functioning spaces, every single time.
NR12 manages 30+ high-end properties across Olbia, Pittulongu, Golfo Aranci (and soon La Spezia) — from stylish studios for couples to multi-bedroom villas with panoramic terraces. Every listing is hand-selected, designer-furnished, and fully equipped: fast Wi-Fi, CREO kitchens, beach towels & parasols. There’s something for everyone — and no two homes are alike. Explore all properties.
Our strength is the team behind the scenes. Founder Floriana leads client relations and strategy. Kristina directs operations and quality. Anastasia shapes the design language. Alejandro ensures maintenance is precise and fast. Diego manages laundry and inventory so essentials never run out. This owner-run + in-house model delivers reliability you can feel.
We turn holidays into stories. Planning a proposal, babymoon, or remote-work escape? We’ll match you with the right home and add thoughtful touches — welcome gifts, grocery pre-stocking, curated local tips. Every guest is supported by a real human. For ideas and itineraries, visit the RENTAL12 blog.
Skip ZTL stress. We offer secure, video-surveilled parking at Via Sassari 20 — just outside the ZTL and a 3-minute walk to most central listings. Pre-book at rental12.com/parking. To avoid fines, see our Olbia ZTL guide.
Travel should feel free. Our terms are clear and guest-first. Most bookings include full refunds within the stated window — no hidden fees or admin charges.
Buildings are newly built or fully renovated with an A2 energy policy; new projects adopt solar; operations use eco cleaning, recycling, and an increasingly electrified fleet. It’s better for Sardinia — and for your stay.
Issues happen. Our typical response is under 30 minutes thanks to teams living and working nearby. From blown fuses to key hiccups or early check-in requests, we’ve got you — a key reason for our hundreds of 5-star reviews and consistent Superhost status.
We comply with Italian guest-registration laws and use Vikey for secure, automated check-in: upload ID, access via smartphone — fast, safe, contactless.
With NR12 and RENTAL12, you get more than a booking — you get a hospitality framework designed for Olbia, Golfo Aranci, and the Costa Smeralda: stylish homes, secure tech, and heartfelt service.
From curated design to quick support, from hidden beaches to rooftop views — your Sardinian dream starts here.
