We absolutely loved the apartment. It was spotless, bright, nicely decorated, and super close to everything: St. Martin market is just down the street, the beach, the Old Town, and countless of shops. It locates on a pedestrian-only street so it is quiet at night. It is also near Plaza Gipuzkoa, where the E21 bus shuttles between San Sebastian airport and the city. The outdoor terrace is great. We enjoyed our afternoon snacks & wine there. The amenities were better than expected: even beach towels were also available. M. Carmen was very nice and helpful. She was fast to respond and gave us some tips to local events. We would highly recommend this apartment.
