Who runs RENTAL12
RENTAL12 rents 37 holiday apartments, houses and villas in Olbia and Golfo Aranci, in north-east Sardinia. Floriana Panvini Rosati and Kristina founded it in March 2021 and still run it with their own team in Olbia. The homes are owned by Lion Development S.r.l. (VAT IT02854400906, registered in Milan) and run day to day by NR12 Srl (VAT IT02965030907), which is 70% owned by Lion Development and 30% by its employees. AZULIS is our designer collection and part of the same group.
Both VAT numbers and the holiday-rental registration, IUN F1530 / CIN IT090047B4000F1530, can be checked in the Italian public registers. Some of the 37 homes are let on long contracts at any given time, so the number open for short stays changes through the year; the booking page shows what is free for your dates.
Our mission
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. Our mission is simple: to host consciously.
What owning every home means for you
Three things that follow from owning and running every home ourselves. The Trust Hub holds the documents behind each one.
Every apartment, house and villa in the portfolio is fully owned, without mortgages or bank debt. Your booking sits with a financially stable owner.
We own 100% of the homes we list. Every home is hand-selected, custom-designed and maintained to the standard we expect for ourselves: CREO kitchens, designer lighting, secure Vikey smart access.
Between 09:00 and 22:00 our typical reply to a guest message takes under 6 minutes, and 9 out of 10 messages are answered within 30 minutes. Measured on 5,699 guest messages from 1 April to 14 September 2026, every reply written by a person. In-stay issues: our teams live and work within minutes of every property, typical response under 30 minutes. From 1 November to 31 March the Olbia office is closed for the winter and replies can take up to an hour. Method and hour-by-hour data →

The founders
Floriana Panvini Rosati
& Kristina
Floriana Panvini Rosati (CEO) and Kristina (COO) co-founded RENTAL12 in March 2021. Dutch precision meets Italian hospitality. Every guest decision still crosses their desk. They personally inspect every property twice a year, on top of the per-turnover 70-point check.

From the operations side
How we use AI
Everything we publish starts with a person. Our team researches, checks and writes the first draft — for our website, our guides and our news articles alike. We then use AI tools for the parts of the work that are craft rather than knowledge: tightening structure and language, catching inconsistencies, and translating between the languages we publish in. Every piece is then reviewed and edited by a person before it goes live.
AI does not make decisions here. It does not decide who gets a booking or on what terms, it is not used in any decision about a member of our team, and it does not set a price without a person approving it. Where our systems are connected to each other automatically, those connections move information and produce reports — people make the calls.
Our photographs are real. We do not generate images of our apartments, our buildings or the places around them. Where a photograph has been edited, the editing is limited to brightness, colour and cropping, and never adds anything to a scene or removes anything from it.
Prices, dates, opening hours, distances, safety information and anything we state about law or regulation are verified by a person against a real source before we publish them. When an automated assistant answers you on our site, it says so at the start, and a person from our team is always reachable.
Responsibility for everything we publish rests with Lion Development S.r.l., registered in Milan, Italy, operating from Olbia and Golfo Aranci in Sardinia. If you think we have published something inaccurate, tell us and a person will read it.
