Javier was great host, quick to respond through the app and attentive to what a guest would need to stay in his place. There were some issues communicating with other members of his staff, but he jumped in to resolve any problem quickly. The place was very clean, had all the basics necessary for a comfortable stay and the location is excellent for anyone visiting Madrid. We stayed there a whole month and were comfortable, although I would say that, through no fault of Javier and his staff, the air quality in that area of Madrid and the small size of the studio might not be the most conducive to a lengthy stay; but it would be perfect for a visit of a week or two.
