Ainhoa and Javier's apartment was an ideal base for our stay in San Sebastian. The apartment isn't large, but had everything we needed and a very comfortable bed (we didn't use the sofa bed, so can't comment on that) and an excellent, powerful shower. It's about a 25 min walk into town and beach, but there is a regular bus if you prefer and by staying a little further out, the apartment is good value for money compared to those nearer the centre. Our car was too large for the parking at the apartment, but Javier recommended parking a few mins away, in a car park that was only 3.5 euros a day. we were able to park outside the apartment for loading and unloading.
Ainhoa and Javier made us feel very welcome and we wouldn't hesitate to recommend staying here.
