David is a great host! He waited for me in the studio after having everything clean and tidy!
He explained to me how the heater works and he got me connected on wifi.
The studio is small and nice, all I needed for my short stay in Madrid. It's about 1 min walking to Tribunal Metro Station and 40 min away from Madrid Aeroport by metro or 20 min by car.
The neighborhood is crowded at night, but the bedroom has a sound isolating door which reduces the noise a lot!
The location is quite good, everything in reachable by foot around 10 min or 20 min to Plaza de Esapagna, Gran Via, Sol, El Retiro and other sites.
If I ever come back to Madrid I would take David's place again :)
