This is incredible apartment, that has absolutely ultimate location (5 min walking from beach, 10 minutes from old town, 15 minutes from shopping streets) including underground parking lot. We enjoyed every hour of our stay there. Apartment is on the top floor, very bright and sunny with large windows, spacious rooms with all amenities you might need for a comfortable stay for 4 people. Everything worked as expected and as advertised. Monica is a perfect example easy-going host who really cares about comfort stay of her guests, and was always easily reachable by phone. I definitely can recommend this location if you are looking for great experience in Donostia.
