The place is very well located. It looks like in photos, just that in photos seems bigger.
The walls are very VERY thin, you basically hear everything from neighbors (I refer to music, chit-chat and so on). Overall the place is very good located and the room was clean, if I go back to Madrid I will definetely try to stay there again.
Also MAX was a good host, he showed us on the map the main attractions and explained little things.
PS: the shower is awesome
