Very good location in the city centre, perfect to explore Madrid. Communication and check-in with the service provider hired by Juan Pablo was easy. The flat was well equipped but unfortunately not very clean (dusty floors, dirt under beds and sofa, most dishes and cups unclean ). Size is perfect for four people but probably too small for six. When one of you plans on sleeping on the couch please note that the living room is very noisy at nights. Please also note that the beds are smaller than indicated (1,40 instead of more than 1,50) which is important when planning to sleep in it with a kid. Good heating. WIFI had weak receptions in one of the bedrooms and living room.
