This is a true "shared room in house" unlike other Berkeley options where you get a key from a lock-box to access a room where you never see the hosts. John met me at the door on arrival, showed me around, and did everything to make the stay comfortable.
The bedroom is awesome. The bed is big and comfy with sheets and comforters nicer than I have at home. The bathroom is steps away across the hall and also very clean. John provided towels too.
I had a brief encounter with three very excited and friendly dogs when arriving, but otherwise did not interact with the rest of the ecosystem. The neighborhood is quiet and the house had a minimum of noise from humans and animals doing their usual routines.
All in all, a great Airbnb option. I hope to stay there again.
