Javier's place is in an excellent location: a few minutes walk from Atocha train station, the charming Barrio de las letras, and of course, the Museo del Prado and the Museo de la Reina Sofia. The apartment was impecably clean, it is very nicely decorated, the bed and sofa bed were very comfortable, the AC worked great and it had great amenities. We did not meet Javier but he responded very quickly by phone messaging. He is a very generous host. I absolutely recommend his place.
