Elena was a great host, made us feel very welcome and provided us with a lot of recommendations.
The apartment is accessed through Elena's own apartment, rather than a private entrance, however this did not cause a problem for us. The apartment was clean, tidy and provided us the perfect base to explore San Sebastián. There is a small fridge in the kitchen/lounge and the balcony is a nice addition.
The apartment is about a 15 minute walk from the cathedral, and about a 30 minute walk from the main pintxos bars. There are bus stops very close to the apartment and the buses are good value and easy to use.
Elena was very responsive to messages and we would definitely recommend staying with her.
