If you're looking for somewhere cheap, simple, and friendly in a lovely part of central Madrid, I'd definitely recommend this place. Cachin is a nice guy and a responsive host, the bed is comfortable and the room is quiet and dark. It reminded me a bit of being a student, to be honest, in that it's pretty rudimentary, so if you're after luxury this isn't the place for you. But as a nice place to stay, for a very reasonable price, it's hard to beat.
