We really enjoyed our stay at this lovely flat in Parte Vieja. The location is quite convenient to all the many things to do and see in the old town without being too close to the hubbub. We also found it quite close to the beaches, Monte Urgull, Gros, and the train station. The flat itself is lovely, with all the amenities you might need, including a fully stocked kitchen. We highly recommend staying here if you visit San Sebastián.
