Ed was great - replied to messages quickly. He was there to show us the apartment when we arrived quite late at night. The apartment is very comfortable and quiet with a nice balcony for breakfast, a well equipped kitchen and comfortable bed. The location is a little away from the centre but well served by the U-Bahn. A good local German restaurant is close by with an excellent Bio supermarket at the end of the street. This is a quiet residential area, not a place for partying, which was fine for us.
