It's a really cute and quirky little attic flat. Despite being located in a centric and busy neighbourhood, the windows kept the place quiet and dark during the night. Everything went smoothly with keys and flat was reasonably clean and equipped with all the basic stuff (towels, soaps, kitchen utensils). Only minuses were the lack of a coffee pot (we resorted to instant coffee powder) and somewhat unstable wifi connection (it worked ok with an android phone but not with an iphone). There's no wall separating the shower/bathtub from the room itself, so if nudity is a problem, I'd recommend someplace else, but otherwise it's a good, simple flat to stay in lovely Madrid!
Thank you!
