Kasia’s accommodation is large; it has five bedrooms, a spacious kitchen and a huge living room with balcony.
I stayed in one of the bedrooms with a single bed and a private bathroom. Other bedrooms were occupied by the other guests. Finding a parking spot for the car was not a problem and Wifi connection was good. Kasia was very helpful and informative all the way through my stay. I strongly recommend this accommodation to anybody visiting San Sebastián.
