The location of the appartment was absolutely great, just a minute away from Plaza Mayor and lots of other nice places in Madrid. We never used the Metro, we could easily walk everywhere we wanted to go to. Check in was a little problematic because the door man, who was supposed to give us the key, didn`t know anything of our arrival and he didn`t have a spare key, because the last visitors left them all in the appartment. He finally talked to Alberto on the phone and then we could get in. Maybe a note, what to do with the keys after departure, would be helpful. The beds were comfortable and there was enough space for 4 persons. The air conditioning didn`t work very well and, at least we couldn`t feel anything of it, and it was very hot, just the fans worked well, but were kind of loud while trying to sleep. Would be nice to have some cleaning towels in the kitchen. The bathroom is a real challenge and not very comfortable, when everything gets wet in there, because there is no door for the shower. All in all the location made up for some weaknesses of the appartment itself!
