This is the place to stay in Donostio! Santiago's place is a 5 or 10 minute walk outside the noise of the old town, off a quiet square with public parking steps away from the flat. The beach is even closer, so plan on walking for your entire stay.
The flat is immaculate as if it was completed within the last month. It is bright and sunny during the day, and dark for sleeping. Since you are in the penthouse, there is a deck with a table and chair for coffee and lounge chairs for an afternoon nap in the sun. Although we did not use it, the kitchen is large and pristine.
Santiago is a great guy and check in and out could not have been easier. We could not have asked for anything more!
