We had a wonderful stay at Tom's place. He was always very responsive, the check-in was easy. The studio is small but it has everything you need and the location is very good, 7 minutes walking from Atocha Train Station, from which you can take a 40 minute train ride to the airport.
The studio has all the necessary amenities, very clean and well organized. It is located in a quiet neighborhood, but very close to the center, 30 minutes walk to Plaza Mayor. Overall, we enjoyed everything!
