The room is pretty clean. I was comfortable sleeping in it. The area is 6 minutes walk to Sol which is the main center of Madrid. It is also 3 minutes walk from Tirso De Molina Metro Station Line 1.
The building is pretty old. Getting into the unit scares me, because it has a sensored light that it turns on but turns off right away. Opening the door to the unit takes a long time where i end up getting shut down by the sensored light and it gets very dark and scary. Theres a ~15 meters hallway going to the kitchen and bathroom and the light is just a christmas light where sometimes it gets pretty dark, the floor squeaks when you step on it.
The host is very nice tho, i can not complain about her. She is very sweet lady.
