Walter is a nice guy, who answer really fast and tried to cope with the situation. Unfortunately he swapped our booked silent backside appartement with balcony (no. 21) with a really traffic congested and westfacing/melting (not allowed to open the windows) flat without balcony (no 33), with leftover food in the fridge and a white towel with yellow spots in the bed drawer (ew). Beside that we didn´t get the remote to get our car out of the parking area until day 3.
