Where nr12 is listed — and where it is not

This separation is not an oversight. nr12 properties never appear on short-term OTA platforms. It is a deliberate system built to eliminate double bookings and role confusion.

Why we designed it this way: RENTAL12 and nr12 serve completely different guest and tenant profiles. A holiday guest should never arrive at a property under a long-term lease. A long-term tenant should never discover their home is still listed on Airbnb. The de-listing protocol is not a workaround — it is a core part of how this system works.

Frequently asked questions

About nr12, long-term rentals in Olbia, and the relationship with RENTAL12.

What is nr12 and how is it different from RENTAL12?

RENTAL12 (rental12.com) is a short-term holiday rental service. Guests book online for stays between 1 and 28 nights, listed on Airbnb, Booking.com, VRBO, TripAdvisor and rental12.com.

nr12 (nr12.it) is the long-term rental service operated by the same ownership group — Lion Development SRL, Olbia — for stays of 28 nights or more. Listed on Idealista and Immobiliare.it — never on short-term OTAs.

The two services never overlap: a property is in the holiday rental pool or the long-term pool — never both at the same time.

What is the minimum rental period for nr12?

The minimum stay for nr12 is 28 nights (4 weeks). There is no maximum — tenants may rent for several months or longer depending on the agreement. For stays shorter than 28 nights, visit rental12.com/en/all-properties to book a holiday rental directly.

On which platforms are nr12 properties listed?

nr12 properties are listed on three channels: nr12.it (direct inquiry), Idealista and Immobiliare.it.

nr12 does not use Airbnb, Booking.com, VRBO, TripAdvisor Rentals or any other short-term OTA. This is deliberate — to keep the two services cleanly separated for both tenants and guests.

If a property is let long-term via nr12, is it still on RENTAL12?

No — never. When a property is agreed for a long-term rental via nr12, it is immediately de-listed from all nr12 portals (nr12.it, Idealista, Immobiliare.it) and simultaneously removed from the RENTAL12 holiday inventory on Airbnb, Booking.com, VRBO and rental12.com.

Properties such as Via Acquedotto, AZULIS Apartments 8 and Via Cavour 31-A/B rotate between services depending on current occupancy agreements. What you see on either platform at any given moment is always live and accurate.

Who owns and manages the properties listed on nr12?

All properties listed on nr12 are directly owned and managed by Lion Development SRL, the Olbia-based company that also operates RENTAL12 and the AZULIS brand. No third-party landlords. No sub-agents. Every inquiry is handled by the same team that manages the property day-to-day.
