Although the location is not the nicest part of Berlin, it is extremely convenient for public transport (including a direct bus to Tegel airport), and a large supermarket is very close by. We used the apartment as a base for seeing all the main sites of Berlin. Andreas communicated very promptly and helpfully, even picking us up from the bus stop and showing us the important places in the immediate area. His neighbour Herr Schroeder was also very helpful.
