The apartment was clean, well set up and comfortable. Mario and Carmina (Francisco's parents) were very welcoming and helpful. As others have said, they live right nearby and were on hand for any help or requests. The location is fantastic, within easy walking distance to all the major sites but in an area where there are many local tapas bars and restaurants. Some people have mentioned noise but we found that if the shutters were down and the windows closed, it was not intrusive. Also, it seemed to us that some noise was inevitable if you want to be centrally located. As a bonus for those who like their vegetables there is a restaurant/tapas bar right below the apartment that has friendly staff and a very good list of vegetarian meals- as well as very interesting meat dishes.
