This is a wonderful house to stay in and a wonderful area to explore Donostia from. The house itself is very homely and welcoming. It has everything you would possible need for your stay and is very clean and comfortable. It has very good wifi which reaches all parts of the house. The kitchen is fully stocked with everything you would need to prepare a full meal. It has two showers which are essential when you come back from the beach with the kids. The highlight of the house is the size of the outside space which is something that is rare to find this close to the beach (it is literally a 3 minutes walk from the most wonderful beach). It is worth choosing this house just for the outside space alone.
However the main attraction of the house is its location. It is only a couple of hundred meters to the beach. It is is only about 50 meters to the nearest restaurants (which is friendly and serves lovely food and drinks btw). And yet it retains its privacy because it is on a very quiet pedestrian street. The area of Antiguo is a very genuinely Basque area of San Sebastian and you feel like you have lived in the city all of your life after a few days in this wonderful "barrio". I would highly recommend staying here
