My friend and me, we visited San Sebastián for two days and stayed at Eva's place. It was a great experience: the appartement is very clean with all necessary amenities, the location is perfect, it is situated in a short walking distance to the city centre, bus station and beach. Eva is a very nice and friendly person, she is punctual and easy to communicate with. Her advise and information about the places to visit were very helpful.
I would definitely recommend Eva's place!
