The apartment was great-- a charming flat on the third floor (fourth floor for us Americans) of a building in a wonderful area within walking distance to much of what we wanted to see while in Madrid, e.g. a ~5 minute walk to the Prado and ~15 minutes to Plaza Mayor. It was even more spacious than we imagined -- three bedrooms along a corridor, a nice living area and nice separate kitchen with eating area. We really liked the mix of vintage and new decor -- it felt very cozy and was warm even in the winter when we visited. The apartment is older and has lots of character (including a few floor tiles that were loose, so just watch out for that). Recommend!
