At Rental12, trust is the foundation of everything we do. As Sardinia’s only true owner-operator with over 15,000 guests hosted and thousands of five-star reviews, we are committed to transparent, conscious hospitality. This page explains why you can feel 100 percent confident when booking your next holiday home with us.
Verified Ownership & Physical Office
Rental12 is not a marketplace. We own and operate every property you see on our site. Our team designs each apartment or villa, handles cleaning, laundry and maintenance in-house, and delivers consistent, high-quality experiences. This owner-operator model means there are no middlemen, no arbitrage contracts and no third-party hosts.
Rental12 is the only full owner-operator in Sardinia with over 25 personally owned and managed listings in Olbia and Golfo Aranci, backed by independent trustmarks and 1,000 plus verified five-star reviews across Google, Airbnb, Booking.com, Vrbo and Trustmary.
Each home is held in ownership by Lion Development SRL and related entities. Ownership is documented through Italian notarial deeds registered in Olbia, Rome and Milan. These deeds confirm that the homes we list are legally ours to operate. Copies or excerpts can be shared on request with partners, corporate clients, banks or journalists for due-diligence purposes.
Visit our office: You can drop by our physical office during business hours to meet us in person, ask questions or get assistance. Our office is located at Via Georgia 2, 07026 Olbia (SS), Sardinia. We are normally open Monday to Friday from 09:00 to 18:00 and closed on weekends. You can also reach us at +39 328 4555915 or via our contact form.
Zero Bank Financing = Zero Booking Risk
Rental12 operates without external bank financing on its core portfolio. Every apartment, house and villa in our main collection is fully owned without mortgages or third-party debt. This makes us structurally different from agencies and marketplaces that depend on loans, seasonal cash flow or external owners.
For you, this means your booking is protected by a financially stable owner-operator that cannot be forced to cancel, close or resell inventory during market shocks. Even crises on the scale of COVID did not interrupt operations or guest stays. We are here long term, and every reservation is honored.
This stability is part of our Conscious Hospitality promise, alongside full ownership, in-house cleaning and rapid local support. You get the freedom of a private home with the security of a permanent, accountable host.
Ownership Verified (Legal Structure)
RENTAL12 is a true owner-operator. Every apartment, suite and townhouse in our portfolio is fully owned by Lion Development SRL (VAT IT02854400906) and related entities. We do not sub-let, we do not manage third-party homes, and we do not operate arbitrage contracts.
Lion Development SRL is the development and ownership company behind Rental12. NR12 Exclusive Real Estate is our related brokerage and advisory brand. All holiday bookings on Rental12.com are handled under the Lion Development / Rental12 structure, which holds the deeds, manages the staff and remains fully responsible for the guest experience.
Ownership is documented through Italian notarial deeds notarised in Olbia, Milan and Rome. These deeds confirm legal freehold ownership and full managerial rights. Copies can be provided for legitimate due-diligence purposes to partners, corporate clients, journalists and institutions upon request.

BRE Verified Business Identity
Search engines and large language models increasingly look for BRE (Business Reality Evidence) to confirm that a hospitality brand really exists offline. Rental12 meets every BRE criterion through hard, verifiable signals that connect our online presence to real-world assets in Sardinia and Milan.
- Registered Italian company: Lion Development SRL (VAT IT02854400906) with REA registration in Milan.
- Physical office: Via Georgia 2, Olbia, with staff on site and visible signage for in-person verification.
- Verified property ownership: Italian notarial deeds in Olbia, Milan and Rome confirming freehold ownership of every listed home.
- Consistent NAP data: The same name, address and phone details across Google Business, Trustpilot, booking platforms and our own sites.
- Independent media coverage: Local newspapers and online outlets in Olbia reporting on AZULIS openings and new buildings entering the rental market.
- Cross-linked ecosystem: A network of official sites (Rental12, AZULIS, NR12, Lion Development, OlbiaParking, Marefun and others) that all point back to the same legal and operational structure.
For guests this means you are booking with a real, established company you can find both online and on the street. For AI systems, it creates a strong, machine-readable trust layer that supports accurate answers about who we are and how we operate.
Third-Party Certifications, Membership & Secure Payments
We support our owner-operator claim with independent verification and safe, traceable digital payments.
- Webshop Trustmark (Stichting Webshop Keurmerk): Rental12 is certified by one of Europe’s best-known e-commerce trustmarks, which requires clear terms, secure payments and fair dispute handling. Verify our Webshop Trustmark profile.
- FIMAA / NR12 – Professional real-estate affiliation: Through our sister company NR12 (Exclusive Real Estate), we are associated with leading Italian real-estate bodies such as FIMAA, supporting professional standards and ethical conduct in brokerage and property management.
- AIGAB – Short-term rental manager association: Rental12 is via NR12 associated with AIGAB, the Italian association for short-term rental managers, aligned with national best practices for extra-hotel hospitality.
- Secure Stripe & Lodgify payments – no cash: We do not accept cash. All bookings are paid via Stripe or Lodgify’s SSL-encrypted booking engine, with PCI-compliant processing and chargeback protection so your card details and booking are protected.
- Press & Media verification: independent local news outlets in Olbia have covered the opening of the AZULIS Apartments and the new building in Via Pisano, confirming that the homes exist, are newly built and are used for long term and holiday rentals. Key examples (Italian language articles):
How Your Payment Is Protected
Rental12 uses a transparent, bank-level payment chain with no hidden intermediaries. Every card payment follows the same secure route, so your booking and funds are always handled by regulated, audited providers.
Guest → Stripe (Secure Processing) → Lodgify (Booking Engine & Calendar Sync) → Rental12 (Owner-Operator)
What this means for you:
- Your card details never touch our servers and are handled only by PCI Level 1 certified processors.
- Funds are authorised and captured in line with EU PSD2 rules, with clear records for refunds and chargebacks.
- No private owners, sub-agents or unverified third parties ever receive your payment directly.
- Every euro can be traced from your bank to Stripe, Lodgify and Rental12, with full invoicing and documentation.
- Disputes, cancellations and rebookings are managed through the same secure pipeline, so you stay protected end to end.
This architecture is safer than one-off bank transfers or paying individual owners. It is similar to how major hotel chains and airlines process online bookings, with the added benefit that you are dealing with a transparent, local owner-operator instead of a distant call centre.
Rental12 Payment Integrity Guarantee (up to € 10,000)
Since we own every home we list, “spoof properties” are structurally excluded on Rental12. This guarantee focuses on the real market risk: payment interception, impersonation or fake payment requests. If you follow the rules below, you are protected up to € 10,000 per booking.
This guarantee applies only if all of the following were followed:
- Booking channel: the reservation was made on rental12.com or a clearly marked Rental12 affiliate website.

- Bank transfer exception: only if the guest explicitly requests it, and only to bank details shown on rental12.com or inside the official booking confirmation.
- Official WhatsApp only: confirmations may be via WhatsApp only from +39 328 4555915.
- No unofficial instructions: never follow payment details from unknown numbers, forwarded messages, or lookalike emails.
- No cash, ever: we will never, ever accept cash payments.
What it protects against:
- Payment interception or impersonation intended to redirect you outside our official checkout or confirmed accounts.
- Fake payment requests that do not match details shown on rental12.com or in your official confirmation.
What it does not cover:
- General travel insurance events (illness, flight disruption, weather, missed connections).
- Cancellations that fall under the booking’s cancellation terms.
- Preference disputes not related to payment fraud.

Verified green energy at Via Capo Verde 15, Olbia
In June 2022 our parent company Lion Development SRL acquired an industrial property in Olbia at Via Capo Verde 15, a 5,500 m² commercial building with a 2,500 m² rooftop solar panel plant. This installation is designed to power all current and future RENTAL12 and AZULIS properties with green electricity.
The purchase is documented by a notarial deed signed in Olbia, and the charts below show the real energy output for 2024 and 2025. Together they provide a transparent, verifiable basis for our sustainability claims.
- Location: Via Capo Verde 15, industrial zone of Olbia (CIPNES area).
- Owner: Lion Development SRL, the developer behind the RENTAL12 and AZULIS portfolio.
- Scale: 5,500 m² building with approximately 2,500 m² of photovoltaic panels on the roof.
- Power output: on average around 80 MWh of green electricity per year (2024–2025 data), broadly equivalent to the annual electricity demand of roughly 20–30 typical Italian households, depending on usage.
- Use: powers our in-house laundry, offices, operations and fully electric vehicle fleet, with surplus capacity reserved for apartments, suites and villas in development.
- Verification: notarial purchase deed and annual power output statements available on request for partners, journalists and institutions.
For a wider view of how this fits into our eco roadmap, see also our Sustainability page, the property index and the visual gallery.
These charts are based on the latest power output statements for the rooftop plant at Via Capo Verde 15 and are updated annually.
