Stayed here for a week before traveling to the Andalusia region, couldn't have been better. Roberto is a kind host, going out of his way to provide a comfortable stay. My Euro-American adapter broke during my stay and he was generous enough to give me one of his own. Private bathroom is very nice, and for a young backpacker I have to say I hadn't come across free access to a washing AND drying machine in the same place for a long time!
Neighborhood is urban and fun, very central, walking distance to some of the best sights and bars in Madrid.
