Ben is an excellent and friendly host with a good design sense.
The room is white, bright and furnished in quality minimalist style with high ceilings and hardwood floors. Very quiet, very clean, good kitchen and bathroom with a nice stall shower (American renters note: showers are not something to be taken for granted in Germany. Many places only have a tub.)
The attached private terrace is a lovely place to have your morning coffee.
Only con: this is a quiet residential area. While there is grocery store very conveniently across the street, and a tram stop right around the corner, you will have to travel a bit to find urban activities and restaurants.
I highly recommend Ben's Airbnb.
