This is a beautiful and very comfortable flat. I went there with my baby and my parents and we had an amazing stay. The flat is very spacious, clean and on hot days a perfect escape from the heat (air con is working really well). The location was perfect for us - very close to the university, close to a beautiful, big park and near lots of shops, cafes and restaurants. Very nice and non-touristic area. For those who want to see the touristic part of Madrid this flat is perfect too as the centre is easily reachable by metro.
Highly recommend this place.
