Asier’s place is great for large family or sharing as it has good communal space and 3 double bedrooms. The area is a 10 minute walk from San Sebastián Old Town which was easily done. Great beaches close by.
The apartment is on a square so lots of bars and restaurants are close by. This is a lively area so be aware that it may be more noisy in peak season.
In summary , a lovely apartment and a very helpful host.
