Ander is an amazing host and responds super fast. He knows a lot about the area and will provide you the most delicious food options San Sebastian has to offer. It is a 20 minute walk to the Old City but the walk is necessary after getting stuffed with pintxos. However, there is also a bus right in front of the apartment making the old city pretty accessible. Overall, the apartment is great, the host is great, and I had a great experience in San Sebastian.
