Fernando was a great host, very eager to help us in any way possible. He met us as agreed and even helped us with our luggage both when we arrived and left the accommodation. He gave good tips in and around Madrid and was always easy to get in touch with.
Location was very good and easy to reach from Atocha and by subway. Even though the location was central, the actual street was peaceful, just nicely away from the busier streets.
Flat was as described, with beautiful views, and in great condition. Flat had nice "attic" atmosphere, but notice you need to mind your head here :) It is also the fifth floor and without elevator.
We were two persons staying over two nights, and for that purpose this place along with this host was perfect choice.
