The big plus is the location in La Latina neighborhood, very close to the metro and lots of nice places.
Unfortunately, there are a few minus points which can probably be easily fixed.
-	Bugs in the apartment
-	Dust in the hallway wardrobe
-	Persistent stale smell in the bedroom
-	High noise level: from the street (bedroom is at the first floor, facing the street), from construction site nearby, from the central heating unit and the room heaters, and from the neighbors (thin walls)
On top of this, when we checked-in a co-host asked us to take pictures of our passports (we agreed but this never happened to us on AirBnB).
