First of all I’ve never met Luis in person, but I got extra quick answers to my questions. The location is amazing (for me the best part of Madrid). BUT! This area is extremely busy during the night as well so this place is really loud. We spent 2 nights there and we couldn’t sleep at all. So if somebody is sensitive to the noises get some ear plugs!! The flat was nice and authentic. When I booked the room it was I bit expensive for the value, but it’s in the center, so I don’t want to complain.
