It was a great place with very nice owners. Everybody already mention in their reviews how stunning the views are from the house. But the house itself is very cozy and comfortable too. Pilar and Mikel were extremely nice. They even greeted us with some food on arrival. We were very tired to drive to supermarket, so this gift was very helpful.
The only thing, which was missing during our week long stay was weather. We had 2 good days out of 7 (raining on all other), but it was enough to fall in love with San Sebastian. Parking in the center of San Sebastian could be a problem, but we found Kursaal being a good choice. It's not free, but not expensive either and it is very close to main attractions.
