Most of the highlights of San Sebastian are within a 15 min walk from the apartment. While the bedrooms allow for 6 people, the living room is not suited for six people being there for the entire day, but it is great for relaxing in the evening. The apartment does not have AC, but it does not warm up quickly and if you open the windows in the evening, then you can cool it down easily.
The welcome was nice, with local specialties left for us in the apartment.
Jon was very quick to respond to my messages and resolved any issues we had quickly. He also gave us good tips for things like restaurants and sightseeing.
