We (3 people) stayed at Katharina's airbnb for two nights to visit family around Berlin.
Katharina is a very kind, laid-back and flexible host. The check-in is uncomplicated and the accommodation has a Mediterranean flair thanks to the unique garden and the tiles that reminded us of Spain or Portugal. :)
We could park our car right in front of the premises and my small dog loved the beautiful backyard.
All in all, I would recommend this accommodation for a short trip to Berlin if you have a car and are seeking for a quite place to stay at.
