The house is just as described, and of unbelievable beauty. Gym, hot tub and sauna all available for use. Only problem is how large it is ; takes 3-4 flights of stairs to get from one part of the house to the other.
House is about a 10min taxi ride from San Sebastian (€9-€13) and the beach is at a walkable distance (30min approx.).
Host is very friendly and easy to reach.
Had an amazing stay!
