Alfonso was a pleasure to deal with and the apartment is better than the photos! We came for the marathon and Alfonse took care of us during our stay. On the day of check in he phoned we when we arrived and personally showed us round the apartment and answered any questions we had about Madrid. Throughout the stay is his communications was excellent.
The apartment is in a great location and you can walk to all the major sights. Furthermore you are spoilt for choice with tons of bars and restaurants just down the road. The apartment is also very well equipped and has everything you need for a stay in the great city.
I would recommend his apartment any time. I hope you have a great stay!
