It is a 5 stars place, near Roberto is Unico Hotel ;).
Me and my wife had a wonderfull vacation in center of Madrid. The place is just 2 minutes from Plaza Colon.
We saw most of the Madrid by foot, thanks to the great position of Roberto`s apartment!
Only good words about this place, rent it fast, it`s worthy!
Roberto is very well educated and likes to have guests in his house.
