Our host made us feel very welcomed when we collected the keys from the office only a block away. The flat was beautiful and had amazing view of La Concha. It was located in the middle of the beach and was really comfortable and nice with lots of books to read and relax. The rooms were very spacious and the terrace was the best part of the house where you could do everything. I would totally recommend Costa La Concha as the best place to stay during your visit to San Sebastian
