Easily the best apartment I've ever booked in a city via airbnb. Peter was extremely accomodating, and we really felt at home.
The apartment has a number of unique features- a piano, a custom lighting system, a huge white wall to use the projector, etc. Laundry and a well stocked kitchen were also great.
The location is also amazing, we were able to walk to everything we wanted to do in Kreuzberg. Would stay again
