The apartment is in a very quiet suburban area of Berlin. It is as is in the pictures in the very back of the building.
It should be noted that you have to go to a property management company to pick up the keys to the apartment. If like me, you are travelling with 2 pieces of luggage and use public transport this is very difficult. I think this is something that should be in the listing itself. As it was I was told about this after I had made the reservation.
I didn't meet Gisela as she lives in Munich and I found it quite difficult to communicate with her.
