The apartment is great located in the center of Madrid, a quick walk from Sol station. The apartment is one of four, tightly converted flats. Due to location of the apartment it is quite noisy and I would recommend earplugs. My husband is a heavy sleeper and slept OK. Situated on the first floor, the apartment would not be ideal if you don't like stairs. I wouldn't recommend for four people/adults it would be a very tight fit and there is no door between the main bedroom and pull out sofa. The bathroom wasn't cleaned properly on arrival and there was black hair on the floor - we are blonde. The apartment is well worn by many travelers and needs a good paint, there are black marks from suitcases etc on every wall and door, even in the bathroom. Pillows need replacing. Bed is OK. Kitchen very well stocked. TV's do not have English channels, if you worry about that kind of thing. Shower pressure was great.
