I loved the Airbnb a lot! Leona & Gareth are very friendly and open persons. They are very interested in the guest but also know what privacy is. If you have any questions about 'What to do - Where to eat' they know the answer :)
It's a perfect location for people; who like their sleep after a long day of sightseeing.
The workdesk in the room is big enough to work on.
I will definitly come back, when I am in Berlin.
