A really nice apartment! We were sent very precise information on how to collect our key since we arrived after the office was closed. The apartment was beautiful and very clean. Despite not having an open office they answered within minutes on messages.
The location of the apartment cannot be beat! We had never vistited Donostia before, yet found ourselves within walking distance to everything- 10 minutes to the old part, 15 to la Concha Beach (although Zurriola beach, just 3 minutes away was just as nice, and less crowded). If we come back- this is where we will stay!
