Clean and as pictured, great location and value but the exception and reason for not giving 5 stars is that noise is an issue. Given that all the rooms in the building are rented out as Airbnb, there is no incentive for people to keep noise levels and excessive partying to a minimum. If you want a quiet place, this isn't the best option. I also did not connect the dots with staying in Malasaña and what that could mean in terms of dynamic so that's one me.
I wrote the host about this through messages but got no response so I went to talk to them in person at reception the next day and Violeta helped me a ton. She was really kind and excused herself on behalf of the disruptive guests. In sum, great place and nice/clean but noise is the only downside (the parties and screaming and music did not happen every single day but often enough, 4 times during my 1 month stay)
