I strongly recommend staying at this Airbnb. The room was private and clean and Susanne with her family are very kind. Apart from staying in your room, you are able to use the kitchen and enjoy the garden. The area is really peaceful and quiet, however it is not far from the Tram, so it's not a problem to reach various parts of Berlin easily.
To sum up, thanks for being such a great host and hopefully see you again :)
