The room is very well located close to the center of Madrid.
Near the Metro and the Atocha train station. There is also a Carrefour nearby that is open 24 hours.
The space is clean and tidy.
The bed is comfortable, and the room is small, but certainly adequate for a few days' stay.
Negative:
there is no air conditioning.
There is only a fan in the room.
Since the room is located on the top floor of the building, I sweated a lot during my stay.
During check-in I was not told that I had a permanent place in the fridge.
My bottles of water and food had disappeared from the fridge during the second day.
The shelf in the wardrobe has fallen down several times as it is not properly secured and needs to be replaced.
I would stay here again but not during the hot summer months.
