We spent 8 nights staying with Maria Jesus. The apartment was very easy to walk to from the bus station. We had a lovely welcome with wine and meats. The apartment is very clean and light. The room was very comfortable with a great shower in the en suite bathroom. It was about a 5 minute walk to the nearest beach past lots of very cool bars and restaurants. It's about 15 minutes to the Old Town and La Concha beach but it is a very nice walk.
We had breakfast with Maria every morning and she helped me a lot with practising my Spanish. She is a very warm and interesting lady. Would definitely recommend a stay here if visiting lovely San Sebastián
