My friends and I stayed there for one night, and the location is perfect since is close to the Atocha train station.
The apartment has pretty much everything like in photos, but you have to have in mind the size of the beds. There were nine of us, and we actually didn't have a place to sleep, so we had to improvise :).
And also, the furniture has some stains and it doesn't look really clean but as I said, we sleep there one night, so it was quite ok.
