We arrive at Madrid very early in the morning (<9am) and Francesco let us leave our bags in the room in advance. He welcomed us with very good recommendations to visit in the city. He was always very respectful with us.
The room is located in the 3rd floor of a building in a very central area, close to Lavapies, a nice area to walk. It is also close La Puerta del Sol (10min walking) and La Gran Via (20min), to Del Prado (15min) and to Atocha train station (20-25min).
It is really close to a metro station, less than 2 minutes walking. That means that you can easily go to cool places like Chueca and Malasaña.
The room has an OK size. The bed is good and it is not cold at all during the night. The main issue with the room is that there are not shelves to put your clothes/shoes/luggage. The private bathroom is also OK but be careful with the shower: if you open the faucets too much you will flood the bathroom and, because there are no sinks outside the shower, it will take some time to dry out.
In summary it is a very good deal if you are looking for a central place close to the metro and to main turistic points in the center if the city.
