We really enjoyed staying at Carlos' place. He is a superhost, very attentive and friendly. He helped us with all the necessary information and facilities,and even helped us with the transfer to the airport early in the morning.
The whole apartment and the room we lived in was very warm and comfortable.It is well located close to the airport, metro station Barajas (just 100 meters), small bars,restaurants and a supermarket.
We would definitely like to stay here more days, and will keep this place in case of our next visits of Madrid,
