We had a wonderful stay at the apartment. It was clean, comfortable, and so centrally located. For those who are bringing a car, parking was located right across the street which was convenient (although a bit expensive but that is for the entire city’s parking in general!).
The apartment was extremely clean, quiet at night, and in a safe neighborhood on a well-traveled street. It’s only two blocks from the ocean and has a grocery store a 3 minute walk away. We were able to use the in-unit washer/dryer which we really appreciated. Additionally, the apartment in located in a neighborhood with a ton of restaurants. The kitchen is also fully stocked with any equipment you might need if you choose to cook! Everything is close in general in San Sebastián and the old town could be reached in ~10-15 min walking.
I would absolutely choose to stay here again and hope I get the chance to if I return to San Sebastián.
