The apartment is perfectly located, only a few steps from the beach and some good bars/restaurants.
Clara and Vanesa are both very nice and communicating with them was always very efficient.
The apartment is very spacious and equipped with all the things you need. Unfortunately, the wifi didn‘t work during our stay - this was the only downside.
All in all we would definitely recommend this place and book it again if we‘d come to back to San Sebastián.
