Location, location, location!!! The building it literally the first building from the beach at Concha (just across the street). The area is not as touristy and other areas in San Sebastian, so many of the restaurants require a bit of walking or a taxi ride 5 - 6 EURO each way, or 20m walk.
The view is absolutely stunning! The apartment is clean. None of the bedrooms have in-room bathrooms. The kitchen is tucked away in its own room near the bedrooms, and far from the living area, which took some getting used to.
One thing note, their is no AC. We were concerned especially because we arrived during a heat wave. But the windows open up completely so the apartment is very airy and no AC was needed. Nonetheless, when we expressed our concern, the host brought us some floor fans, which were hardly needed.
Overall great experience. My family loved it a we would definitely stay here again.
