Ibon's flat is the perfect base to explore San Sebastián. It's a 15-20 minute walk to the old town but the area around the flat has lots of lovely bars, restaurants and bakeries! The flat is great, really clean and has everything you need. The shower is really powerful and the bathroom is spotless.
We had a fantastic couple of days in San Sebastián. Ibon doesn't speak much English but my husband speaks some Spanish so we managed fine.
