This place is in a great location! That being said, if you are not used to big city’s noises during night, I would recommend ear plugs for sleeping. This small apartment is newly renovated and the balcony is nice.
We stayed 4 nights and there was a little safety consern with the building’s door as it didn’t lock. Arturo answered this consern quickly and a handyman fixed the door. Overall, everything in Madrid is accessible from here, so I would recommend!
