We had a very comfortable stay in Ainhoa's flat. It has modern fittings/bathroom, a nice little balcony for enjoying afternoon wine and even laundry! Ainhoa was super accommodating and kindly left us extra towels for the beach and arranged for an early morning taxi. Her flat is about a 5 min walk to the surfing beach, which in my opinion is the best one as it is really large with space for swimmers and surfers alike. We found it hard to get a taxi in San Sebastian (you have to know where the taxi stands are), but it was only about a 15 min walk or less from the train station. Though the street was not that busy, it did get loud in the early morning, but you could cut the noise by pulling down the heavy window shades they use in Spain. San Sebastian is pretty small, so it was an easy walk to the old town which is more touristy and has the highest density of pinxos and bars for the evening.
