Excellent location, perfect place that fits up to 4 adults. Location is very good and commute very easy. About the stairs and the apartment being on a 7th floor, I believe is not a problem as in Berlin you usually have to go up 4 or 5 floors walking. Marc was very responsive at any time. I would like to stay here the next time I am in Berlin. Also you can find good breakfast/lunch places as also restaurants and bars very close to the apartment.
