The place is pretty nice, the location is top! Very close to all public transports (bus/train/metro). The "big" in the title must be a wrong automatic translation. It it not big, but has sufficient room for 2+2 for a few days. You'll be in the city most the time anyway. But to mention is the entire houses ventilation system that goes right trough the apartment and makes a constant noise, wich is very annoying especially at night, when its silent around. That must be new, because no other review so far mentions this. And that is also the only major downside, another one is, that the windows are not really tight, so there is a permanent draught in the room. But that should be easy to fix, and is maybe only a problem in winter.
Another small problem could be solved pretty quickly after we told Marie. She was very helpful in any respect and also gave us helpful advice regarding transport on arrival and some good tips for our stay.
