We stayed in Xavier’s apartment for a week in November 2022.
Good points are excellent location in Old Town, all the main city attractions are walkable, plenty of restaurants around, clean and well equipped apartment (including kettle), comfortable beds, 2 good bathrooms, a childrens playground just outside the apartment which would be great if you’re bringing small children. Javier was a great host. He met us on arrival and explained everything in the apartment. He also met us at the apartment when we were leaving.
Not so good points - the Italian restaurant directly under the apartment can be a bit noisy and there was only Spanish stations on the tv. These are minor points only and they did not detract from the overall good experience.
Overall, I would definitely recommend a stay at the apartment
