Location, location, location! This flat is absolutely perfectly situated for everything you'd want to do in Madrid. Comfortable space with a well equipped kitchen (we brought in food a couple of times) and good heating. And the building had a lift which was great. An easy train ride from the airport, Kristian sent us very helpful instructions and then we walked literally everywhere in town. Good supermarkets, bars, cafes and restaurants nearby. Very close to Plazas del Sol and Mayor. Our check in was easy and communication with our host was excellent. Great place if you are visiting Madrid.
