This apartment was fantastic. Ideal location in old town. Even though the district is very busy, the apartment stays surprisingly quiet. The apartment is clean and well appointed.
The apartment is located over a fish store (not restaurant), so sometimes the living room area has a slight fish odor (more so if you open the windows), but not enough to be too bothersome.
We loved our stay and will definitely return to this Airbnb shall we return to San Sebastián!
