Great location and apartment. The other rooms are airbnb'ed separately so it's really your luck of the draw as to whether you'll get great great housemates for the duration of your stay. In my case, one of the rooms was used by younger backpackers that weren't considerate of the others and used the common like a hostel environment (loud late night conversations, not washing used dishes and leaving them in the sink etc). However, I can imagine that given better housemates this would be an awesome airbnb to stay at in Madrid as it's the best central neighbourhood. The apartment itself is pretty great and Miriam is always able to give some valuable local advice.
