The only good thing is the location.
It’s a tired hotel that needs a total upgrade to a minimum 3 star standard (it’s says it’s already 3 stars!!)
There are allot of prostitutes working at the door of the hotel, as well as the homeless. The air conditioning in the room is not very good a Madrid is a very hot 39c.
The housekeeping is very noisy at 7am with all the banging, and talking and laughing. Most people on our floor had the do not disturb sign on the doors.
