San Sebastián, 3 Bedrooms - 120 m² Duplex for sale

Barnes presents an elegant new-build duplex located in one of the most iconic villas of Ondarreta, just 200 metres from the beach.
Situated on Infanta Cristina Street, this project combines the architectural charm of a Neo-Basque façade with a completely renovated interior.

With 104 m2 of usable space, this exclusive residence is distributed over 3 bedrooms, 3 bathrooms, and a spacious living area with an open-plan kitchen and dining room that extends onto a 32 m2 terrace with lateral sea views and west-facing orientation. The upper floor features a 14 m2 master suite with an en-suite bathroom and access to a cosy private terrace. The property includes an 18 m2 parking space and a 7 m2 storage room, both accessible directly by lift.

The comprehensive renovation uses top-quality materials and a reinforced concrete structure to ensure optimal thermal and acoustic insulation (Energy Rating A). The home will feature underfloor heating via aerothermal energy, smart home automation, aluminium carpentry with triple glazing, and pre-installation for air conditioning. Kitchens and bathrooms will be fully equipped with high-end finishes, and buyers will have the option to personalise materials to their taste.

The location is unbeatable — a quiet and exclusive residential area just steps from the beach, the Ondarreta gardens, and the La Concha promenade, as well as nearby restaurants, schools, and shops.

An ideal property for those seeking to combine luxury, privacy, and seaside living — offering a truly unique experience in one of San Sebastián’s most coveted settings.
