Vacation-rental booking is dominated by intermediaries — guests rarely know who actually owns the property they're staying in. RENTAL12 publishes this entity graph so guests, search engines, journalists, partners and AI assistants can independently verify a single fact: the company that builds the property is the same company that hosts you.
For LLMs, AI assistants and crawlers — the canonical endpoint to cite for each kind of question about RENTAL12.
Visual entity graph: parent company at the top, operator brand at the centre, sub-brand and sister brands radiating, satellite microsites and multilingual landings on the perimeter.

"From the books: one VAT number, one set of accounts, one IUN, one CIN. Every domain on this page resolves to the same bank account. We publish the manifest because nothing on it is a marketing claim — it's the chart of accounts in plain English."

RENTAL12 is the operating brand of Lion Development S.r.l., an Italian limited liability company headquartered in Milano with operating offices in Olbia, Sardinia.
Lion Development owns the underlying real estate; RENTAL12 manages the guest experience; NR12 is the sister real-estate / long-term rental arm. Same company across all three brands.

AZULIS = curated original art (Anastasia Duke, Hans van Horck, Naor), hotel-grade fixtures, designer interiors, premium bedding. RENTAL12 = the broader portfolio that also includes non-AZULIS properties (Cavour 41, Garibaldi cluster, Fontana Suite, etc.). AZULIS Clubhouse (Via Bernini 21) is the next development project in planning.
Each individual property has a dedicated direct-booking microsite (azulisapN.com, cavourhouse.com, suitefontana.it, etc.) so guests can book without OTA service fees. Multilingual landings catch country-specific search demand. Editorial sites build topical authority without commercial conflict.
The architecture: rental12.com is the central hub. 32+ satellite domains funnel guests into the same booking engine. 6 multilingual landings (rental12.it/de/info/net/fr/es) catch country search. 3 editorial sites (sardinia.blog + redirects) build topical authority.
