The location of this place is unbeatable; 1 block from la Plaza del Sol and 2 mins from the metro station and as such easy to get there. You can organize walks to all major tourist sites from there without any problem. In spite of the crowds in the street, the room is very quiet and you can sleep comfortably. The room per se is very well planned, very clean and with amazing 2 balconies; the bathroom is small but you won't need more space than that. I didn't use the common area much (only the fridge) but it was always clean and organized. I'd definitely stay in this place again in another trip to Madrid; highly recommended.
