The location of the apartment is incredible, it was really clean, the bathroom was nice and there's everything in the flat you could need. The communication with the host also worked quite well. Although it has to be said that the apartment isn't very good soundproofed and you could hear a lot from other apartments, the hallway and especially from the street until late in the morning (that just comes with the location I guess).
The bed however was horrible, the mattress was rather old and curved to the middle and the whole thing is in dire need of changing.
