We arrived in the pouring rain, but the apartment wasn't ready for us. Asier was able to accommodate us by letting us drop our luggage at the apartment and pointing out some places to eat before we could get in. He also helped find us parking which was almost as good as having the apartment.
The apartment is perfectly located in a very nice area close to the water and the old town and everything we wanted was within walking distance. The apartment was very pleasant comfortable. There's a great supermarket two blocks away and it was great picking up stuff for breakfast and we even made dinner a few times because we were so inspired by the food in San Sebastian. It's also very nice facing the courtyard rather than the street though for an old building the walls are surprisingly thin and you can easily hear your neighbors. Still, we'd gladly return!
