The good: location.
The bad:
No hot water in showers on most days. On days it did work, the hot water turned icy cold within a few minutes.
Heaters did not work in winter and the place was constantly at 18-19 degrees celsius.
There are in total 4 keys and one passcode to enter the apartment and turn on the lights. Keys have to be used in a sequence and are padlocked together. One of the keys controls electricity. So if one guest needs to leave the apartment, everyone else must sit without electricity.
Elevator only goes up till third floor, apartment is on the fourth floor.
