Our flight was delayed but Dieter, who is caretaker of the place for Ramfis, was waiting patiently for us when we arrived. We got a very nice introduction of the place and loads of "local" information about Berlin :) We had a overall nice stay in a wonderfully quiet neighbourhood and were allowed to keep our bagage at the apartment after our stay due to our flight leaving several hours later - thus we did not need walking around with our bags on our last day.
