Marco is a very lovely and kind person.
He gave us the possibility to make the check in very late in the evening, with no problem.
The room is very big with private bathroom, all is clean and comfortable. Marco's place is very near to the city centre so it is easy to reach all the principal attractions simply walking.
We spent a very special weekend in Madrid and I absolutely would like to advise marco's place to everyone,it's really the perfect location for seeing Madrid.
