Because of a flight delay we arrived at 11 pm to the apartment and Jorg was waiting for us, without problems.
We had a reservation for May but for familiar problems we have been forced to shift the reservation on September.
As by settlement, having canceled the day before departure, we totally lost the amount paid, and paid a new amount for the second booking, but jorg on his own initiative, found a new guest at the last minute, so he offered us a partial refund on the second booking, very very honest man!!!
The apartment is situated 5 mins walk from the underground and it is very good to visit the city, the neighbour is good.
Thank you very much Claudius and Jorg and see you next time in Berlin!!!
