Me and my girlfriend spent in Madrid 2 days and 3 nights. The flat position of the flat is unbelievably central, 10 meters and you are in plaza major. You can reach every place in 10 minutes walking. The apartment is very small but nice and clean. We didn't have too many trouble to make the check-in and find the flat. It would have been 5 stars if it wasn't for the towels which smelled terribily. I would suggest to bring your own towels. For the rest everything was great.
