Things you need to know beforehand:
1) The wifi password is on the back of the router. (do not try to access wifi through the paywall)
2) When you check out, make sure that -before closing the door to your apartment- the downstairs door is unlocked. Especially important if you check out at night, because the other residents tend to lock it and you will get trapped in the stairway...
Other than that: very nice apartment, very clean, and nice staff. Obviously it is a bit louder at night, but we didn‘t mind.
