It is not far from the City Centre and it's close to the U-Bahn (U2 - Vinetastrasse) which is really helpful! The bedroom has plenty of space and the bed is not that bad either. It is however close to the entrance of the apartment which means especially at night you can hear everyone entering the apartment and early in the morning you can hear young children running on the stairs to the levels above you.
But this wasn't a really big problem for me personally.
The housekeeper Andreas is really nice and is able to give you some good advice of what to do and where to go.
