This apartment is a gem, in a perfect location. You can walk almost everywhere. The view from it is absolutely stunning. However:
It is smaller than the photos show, the toilet is especially tiny.
The elevator is also tiny and slow (will fit 2 people). I did not use it at all, and sometimes beat the elevator users. Apartment is actually located at the 7th floor (1st floor is 2 flights of stairs above ground) and 134 steps. Very good for the quads :)
The master bedroom is very small and is the only access to the shower/sink.
The apartment gets quite hot in the summer - especially the gallery and the AC does not manage to cool it completely.
I think it is ideal for a couple, less so for a family.
