Jürgen is a very nice guy and very accomodating. We really enjoyed his place. It was clean comfortable, stylish and in a very quiet location.
It is about 1 hour by metro from Berlin city center. This was good for us because it's a good place to come back to after being in the loud city all day.
We had to leave somewhat earlier than we wanted to because of a really early flight but but overall it was a great stay and we'll be back again when in Berlin! Thank you Jürguen for everything!
