Ricardo was great and we met as arranged. He gave great instructions for reaching the apartment as well as providing a helpful overview of Madrid. He also made some very helpful suggestions for finding good food in the area.
The apartment was just as described and was lovely and central but quiet at the same time and it was really easy to get around the sights we wanted to see on foot. It was very well supplied with all that was needed for a comfortable stay.
I warmly recommend Ricardo and Juan's accommodation.
