We had a nice experience with this flat. The location is perfect to visit Madrid by feet. We were a party of 5 and the apartment was big enough to accommodate all of us comfortably. We had some problems with the air conditioner (it automatically turned on during the night) and the water heater (we had less than 5 minutes of warm water and it took a lot of time to get it again). Two of the bedrooms don't have windows and the beds are a little short according to our flatmates 190 cm tall.
