About RENTAL12

One of the few fully owner-operated boutique hosts in Sardinia. 37 owned & operated properties across Olbia, Pittulongu, Golfo Aranci and the Costa Smeralda. No mortgages. No sub-letting. Every booking handled in-house by the team in Olbia.

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.

Three structural differences

Three things every agency, marketplace and standard Airbnb host lacks. See the Trust Hub for verification documents.

01
Zero Bank Financing

Every apartment, house and villa in the portfolio is fully owned — no mortgages, no leverage, no third-party debt. Your booking is protected by a financially stable owner-operator.

02
In-House Quality & Control

Not a marketplace. We own 100% of the properties we list. Every home is hand-selected, custom-designed, and maintained to the standard we'd expect for ourselves — CREO kitchens, designer lighting, secure Vikey smart access.

03
Under-30-Minute Response

Our teams live and work within minutes of every property. Typical issue response time: under 30 minutes. This reliability is a key reason behind 1,550+ five-star reviews across Airbnb, Booking.com, Vrbo and Google.

How we deliver consistency

Documented 11-section verification on every turnover, signed off in Breezeway by Maintenance Lead Alejandro and the in-house team. Owner-audited twice a year by Floriana & Kristina.
