We had a wonderful time at Jürgen's place. It is a lovely home in a very peaceful area and the description is very accurate.
Transport links into the city are very easy and frequent. If staying more than a few days buy one of the ticket deals available.
As well as all the other sights Mauerpark is a must on the Sunday.
Also, on our way to the airport we went through Kopenick and wished we'd spent a day there too.
All in all we'd highly recommend and will use Jürgen's home again if we go back to Berlin.
