The house is very roomy and can accommodate lots of people. It is near a metro station that can get you straight to the center (7-8 stops). In the nearby area there are lots of convenient stores and supermarkets but not that many restaurants, except for only Turkish ones. The area didn't fill that much safe to be honest though we didn't experience any incident.
The kitchen was fully equipped. Everything was really clean except maybe the bed linens that were for sure washed but there were some remains.
I would recommend this place if you want to stay to this part of Berlin and you will be many people.
