We were traveling from Barcelona by car with my husband, our son and my husband's sister.
Mikel & Ainhoa absolutely lovely & friendly couple! They met us and let to leave our luggage by noon despite check-in time is 3 pm., helped to park our car, gave us city's map and gave us redo where to go and what to explore. The apartment was very clean & quite, with good WIFI and equipped with everything that you might need. We felt like we was in our home. The location is very centric, very close to old town, shopping street and close to the beach. So, we loved absolutely everything! There are so many lovely cafes & restaurants! Parking is 3 min walk from the apartment (25 euro 1 day). Big supermarket and small shops are very close to the apartment, so we bought food there and then cooked it in the apartment. We'd definitely back to San-Sebastian (I think it's one of the most beautiful places in the world) and definitely stay with Mikel & Ainhoa!
