Good:
Great location very close to the city centre. Easily reached by metro.
The room & apartment themselves overall matched the descriptions & pictures.
Very clean room & apartment.
Check-In/-Out were very efficient.
Good cost-benefit ratio
Could be better:
The photos of the apartment suggested a slightly better condition for the building itself.
There was no light in the entrance of the building.
A tall person could not stand upright in the bathroom, especially in the shower.
The descriptions did not mention this. Also, you could hear every single & slight noise from other guests, even lightswitches! Especially since our room is next to the bathroom.
There were so many messages from the hosts, including self-promotion, which became a bit annoying after a while.
Bottomline
Very good apartment, but rather noisy.
