The apartement is exactly as seen on the pictures.
I stayed here for almost 3 months and I can say that I felt right at home.
We did not get the chance to meet Eric personally, but we met one of his sons. They were both really helpfull and nice.
The area is very central, with 2 subway lines close by, Supermarkets and close to one of the good streets of Berlin to go and have a drink (Oranienstrasse).
I can only recommend to stay here.
