The flat is very good, everything perfectly equipped, Albert's care that we are well has been a plus, he has received us and said goodbye, and that we left the flat at an unusual time and with the taxi to the airport at the door, all a detail.
Very good host!.
The area, although it is not Berlin centre, is a very nice residential neighbourhood, quiet, with a supermarket in front and many bars and restaurants nearby.
There is also a shopping area about a kilometre away.
