luxury architect apartments / penthouses for sale Donostia-San Sebastian, Spain

Centre - Next to La Concha beach. Calle San Bartolomé. Magnificent, fully renovated home, ready to move into, right by La Concha bay. It offers partial views of La Concha beach and the island from inside the property, and is just a few steps — around 50 metres — from the beach. Located on the second floor of a stately building with a protected façade of outstanding architectural quality, it features high ceilings, an ideal dual aspect for cross-ventilation, and a spacious entrance hall with a lift as well as a platform lift to overcome the stairs. Layout: The street-facing side, with views towards La Concha, comprises a large 50 m² living room, 2 bedrooms (originally three), 1 full bathroom and a guest toilet. This is a highly sought-after home for being right in the city centre, next to La Concha, with an ideal size for both families and investors looking for a safe long-term asset with strong rental potential. A full renovation was carried out under an architect's project, reinforcing the structure, fitting new Climalit double-glazed windows, and adding acoustic and thermal insulation to the walls, floors, ceilings and façade, both to reduce noise from outside and to keep heating consumption to a minimum. The result is a maximum-comfort home that feels calm and relaxing to live in. Top-quality materials were used throughout, together with bespoke, functional designer furniture and numerous large fitted wardrobes providing generous storage space. Doors, appliances and bathroom fittings are all of premium quality. If desired, the property can be delivered fully furnished and equipped, ready to move straight into. Calle San Bartolomé sits in the very heart of Donostia-San Sebastián's Centro district, just a short walk from La Concha beach and promenade, the Miraconcha area, the old town and the city's main shopping streets. It is an extremely well-connected, highly walkable location, close to public transport, top restaurants, boutiques and everyday services — one of the most prestigious and consistently in-demand addresses in the city. Given its unbeatable location, generous room sizes, high-end renovation and flexibility of use, this property represents an excellent opportunity both as a primary residence in the very centre of San Sebastián and as a secure, high-potential investment.
