Clean, central, modern, hassle free... what more could you want?
The check-in process was very smooth and did not require meeting Mario. The room was sparsely furnished, but had everything I needed. The bed was super comfy and I slept quite well, despite the audible noise of the traffic (the apartment is right on the corner of a rather busy intersection.
The bathrooms were somewhat strange, as the doors had glass panes in them, which made it possible to see into the bathroom to some extent. If it weren't for that I would say that this room/apartment is pretty close to perfect.
