The apartment is in a great location near one of the main train stations. It is in a quiet building, but near plenty of shops and restaurants. It is also walkable to many sights. There is no air conditioning in the bedrooms, so it got a bit warm during this unusually hot summer, but still not a problem. The ac in the living area worked great, as did the washing machine. Communication was fast and easy. I would recommend staying here when visiting Madrid.
