I stayed at Miguel's apartment for 2 nights with my boyfriend and 2 friends while in Madrid. It was a lovely place, very clean and comfortable with many amenities. It's very easy to get to from the airport (take the C-1 train!). Also well connected by Metro, and easy to walk to the major sites. We walked everywhere during our stay. Very close to the tapas on Calle Baja and the Rasto market. The internet connect was great and we were happy to have the TV to catch some of the Olympic broadcasting! Communication with Miguel was good and he left maps and tourist information in the apartment, which we found very helpful. I also loved the large wall map of madrid in the living room!
All in all, a great spot and we were happy to have stayed there.
