This is sort of like staying in a Hostel. There are 3 levels each with several rooms & a bathroom. We had a lock on our door so we weren’t worried and never had issues with the bathrooms being occupied. The room was very clean and we also had a fan in our room which was great as it was so hot when we were there! The location is perfect and the artwork in the apartment was cool. The only downside was check in due to a breakdown in communication (the host didn’t reply to our messages stating we were outside, and we were left waiting for ages). Other than that, would highly recommend a stay here! Good value for money and in the heart of Madrid without any road noise.
