We enjoyed our stay at this flat near Kursaal and Playa Zurriola. It’s a great location; close to everything, but not in a neighborhood that is loud until late in the night. The restaurants and markets right downstairs are very convenient, and if you want to surf, the rental shops and surf schools are right downstairs.
The flat itself is nice, a little smaller than the online pictures, but comfortable. It would be great for the agency to make a few cooking essentials like olive oil, salt pepper, dish soap, and kitchen towels available. Some of the living room furniture is in need of a quick cleaning.
Overall, we had a great stay, and would stay again on our next trip to San Sebastián!
