The short version - I have never booked a "private room" on AirBnb before, and we couldn't have made a better decision. If you're thinking about a different AirBnb, book Yochi's place. If you're thinking about a hotel room instead, book Yochi's place.
They did everything they could to reassure us that their home was our home - and it felt that way.
The long version - my wife and I have never booked a "private room" before, for many of the same reasons others probably don't; but when considering the previous exemplary reviews, the location, and the price, we booked anyway.
When our 4 day/3 night trip was over, not only did we feel like we made the right decision - we felt like it was the best decision. Saying, "I would book this place again" can be cliche on AirBnb, but I hope we get a chance to stay with them again.
+++ The location
+++ Yochi's hospitality
+ The bed was more comfortable than my own, and I'm picky; the sheets, the mattress, and the pillows
+ The bathroom was very clean, and was for us
+ We felt like it was our place
