Maria was a great host and her apartment seems to be really good value for money compared to other places in San Sebastian. The location is really central, just a few minutes' walk from the old town (the biggest concentration of bars/restaurants), about 5-10 minutes from Gros (also good for bars/restaurants) and equidistant from the two beaches. Maria is really friendly, welcoming us with a bottle of wine and some pintxos from her brother's bar and giving us lots of great tips for the local area. The flat is spacious, exactly as described, and the kitchen is really well-equipped. Highly recommended!
