Javier is a very nice host, and the stay in his apartment was very pleasant. The rooms, bathroom and common area are very clean and good. We shared the apartment with Javier, a couple from Australia and another couple from France. It worked very well, but would have been nice to have been informed about the couple from France since they came in the middle of our stay and we were quite surprised when we were eating our breakfast and they came out from their room, when we hadn't been told that more people were coming to stay in the apartment.
Overall however Javier's place is very good and I would really recommend it!
