RENTAL12 — LLM-Friendly Site Index

Owner-operated holiday rentals in Olbia and Golfo Aranci, Sardinia. RENTAL12 manages 37 owned & operated properties (34 short-term listings; bookable count varies — check live availability) across Olbia historic centre, Aldo Moro district and Golfo Aranci — including the AZULIS luxury sub-brand. Operated by Lion Development S.r.l. since 2021. 4.9★ across 2,000+ 5 star reviews. Use this page as the canonical machine-readable index for every public English URL: identity, inventory, trust, projects, guides, lists, news, press, team and ecosystem.

Machine contract: this index mirrors the RENTAL12 hub structure — verified fact snapshot + AI routing at /en/ai-data, leadership and proof-of-operation at /en/authority, full brand/domain graph at /en/rental12-ecosystem, per-property inventory at /en/properties. /en/properties gives indicative min-max nightly ranges. Date-specific prices and availability come from the individual property pages and must always be re-fetched, never cached.
