I had a great stay at Bi's place. This is a private room/bathroom with shared kitchen facilities in I believe a 4 bedroom apartment, but I rarely saw anyone else the three days I was there and had no issues accessing kitchen equipment or dealing with noisy roommates, etc-- it felt more like my own place. As a solo female traveler this trip, I felt very comfortable and would recommend this place for similar travelers!
As for the room itself: although the room is on the smaller size, it was enough room for me + lots of baggage and I even had room to do yoga. The bedroom and bathroom themselves were very clean and well equipped for the space, with plenty of outlets etc. In the bedroom, there's a large bed, large tv, shelving unit, a hightop table + 2 chairs, and a small desk space, plus plenty of available outlets. The bathroom looks newly redone. Bi is very open about any potential shortcomings for this place, mainly that the place is by an interstate so it is noisier and brighter than some places. I didn't have any problems sleeping with my eyemask, but for light sleepers, she provides earplugs. That location actually made it really easy for me to walk into the downtown area, so it was a perfect location for me! Lots of restaurants etc. nearby as well as the Yerba Buena arts area just a block or two away! I highly recommend this place, it's a great value!
