Excellent location. Very convenient for sightseeing Madrid. Carlos is very caring and accurate, everything was well organized on arrival and departure. Our departure was late - at 4:30 PM, and Carlos offered to leave luggage in his office. His presence is discreet and unobtrusive. The apartment is clean, quiet, has good internet. We are very satisfied with their stay in this apartment. We recommend it to all who want to be in the center and still a quiet place. We will surely come again.
