The room was okay. It is very small so more suitable for a short trip.
The location is perfect in a very nice and vivid central area of Madrid and everything is connected well!
The room itself was clean but could have been a bit better. There is not much light coming into the room and very very small. Some appliances were missing like a hair dryer e.g. It can also be quite loud with the neighbors (we can confirm this on a Friday evening)
In general the price was a bit too high for the quality of the studio.
If you plan a short trip to Madrid the room is fine for a few days!
