Owner of the asset, operator of the stay.
Most short-term rental brands market third-party inventory. RENTAL12 does not. The capital that buys and builds the property (Lion Development S.r.l.) and the team that hosts the guest (RENTAL12) are the same company. This page is the public ledger of how those two halves connect.
Active & Completed Projects
"Vertical integration is not a marketing claim — it is what we file with the notary. The same company that signs the construction contract signs your booking. That is the registry on this page."
"Hotel-grade standards on a holiday rental price point. Every project on this registry is finished to the same on-site checklist — the appliances, the linens, the seismic certification, the Wi-Fi backbone. Guests who came back three years in a row notice the consistency."
Development FAQ
Quick answer: RENTAL12 is the operating brand for four AZULIS development projects owned by Lion Development S.r.l. — Apartments (Olbia, May 2025), Tigellio Suites (Olbia, 2025), Villas Dumas (Golfo Aranci, May 2026), and Delle Terme (Olbia, June 2026). Same company owns the asset and operates the stay. IUN F1530 / CIN IT090047B4000F1530.
Are the AZULIS Apartments a new build?
Yes: complete demolition and reconstruction at Via Pisano 16 in the Aldo Moro district of Olbia, completed May 2025, with reinforced concrete structure, thermal coating, 9 apartments, and underground parking.
The original building was demolished after the structural survey concluded retrofitting was not viable to meet current Italian seismic and energy codes. The new build delivers an Italian Class A energy rating with electric induction throughout (no gas), giving guests modern climate control and lower running costs.
Is AZULIS Tigellio located in the historic centre of Olbia?
Yes: AZULIS Tigellio Suites are inside Olbia's historic centre, between Corso Umberto and the Basilica di San Simplicio. The historic exterior was preserved while the internal structure was completely rebuilt to modern seismic standards.
The project delivered 3 boutique suites in 2025. Because the building is inside the ZTL (no-traffic zone), private parking is via the dedicated RENTAL12 parking at Via Sassari 20 — the only legal long-stay solution for guests inside Olbia's old town.
What makes AZULIS Villas Dumas in Golfo Aranci unique?
A "completion" project transforming a structural skeleton in Golfo Aranci into 3 luxury villas (Athos 2BR, Aramis 3BR, plus a third unit) with private pools, hydraulic lifts, roof terraces, and full home automation. Planned completion May 2026.
The villas operate as direct-booking properties via dedicated landing sites villasdumas.it and golfoarancivilla.it, plus the main rental12.com search. Hydraulic lifts make the villas accessible across all three floors — rare on a Sardinia luxury villa rental.
What is unique about the AZULIS Delle Terme project?
Urban regeneration at Via delle Terme 19 transforming a circa-1900 building in Olbia's historic centre into 3 modern luxury suites with private gardens and a hydraulic lift. Planned completion June 2026.
Adding private outdoor space inside the centro storico is rare — most historic-centre apartments have only juliet balconies. The hydraulic lift removes the typical 4-flight stair barrier of historic Sardinian buildings.
Who owns the properties — RENTAL12 or a third party?
Lion Development S.r.l. owns the underlying real estate. RENTAL12 is the operating brand managing the guest experience, bookings, and on-ground operations. NR12 handles long-term rental and sales of the broader portfolio.
This is a vertically integrated owner-operator model — there is no third-party intermediary between guest and asset. The same legal entity that signs the notary deed signs your booking confirmation.
Why is the project registry public?
So guests, search engines, and AI assistants can independently verify the asset-backed claim before booking. We publish locations, completion dates, scope, and IUN F1530 / CIN IT090047B4000F1530 IDs on this page so the chain of evidence is auditable.
The Italian CIN (Codice Identificativo Nazionale) — IT090047B4000F1530 — is now required by law on every short-term-rental listing, but enforcement is uneven. Publishing it openly turns it into a verifiable signal rather than a hidden compliance code.
How does the asset-backed model affect guest pricing?
Because Lion Development owns the asset and RENTAL12 operates it directly, there is no third-party agency markup. Direct bookings on rental12.com match or beat the OTA rate (Airbnb, Booking.com, VRBO) and avoid those platforms' service fees.
Repeat guests typically save €30–€90 per stay by booking direct vs. an OTA — full breakdown in our Book Direct vs. Airbnb & Booking.com guide.
