We are a family of 5 person and we spent 3 days in Stella's appartement. The appartement is modern, quite spacious and well equipped (it can really accomodate 6 people). The neighbourhood is rather calm as well.
The location is great : 300m from tram stop (Hufelandstrasse) which will take you to Alexanderplatz in less than 10'. You will also easily find scooter or bicycle to rent (Lime, ...) in the area. There's a Lidl supermarket at 5' walking distance.
We enjoyed our stay at Stella's place.
