The house was more than enough for our needs and with everything necessary for a comfortable stay.
The bed was nice and we had a nice rest after a whole day walking around Berlin. The area is also very quiet and pleasant. The walking distance to the station was doable and it goes straight to central Berlin. We usually didn't have to wait much more then 5 minutes for the S-Bahn to arrive at the station.
Rainer is a great guy and a great host, he waited for our late night arrival and still offered something to drink and some advices of what to do, see and eat around the area and the whole of Berlin.
He also made us feel right at home and our only regret is not to have more days to spend there.
