Shan's place is in an excellent location and perfect for a solo business traveler. I was at SFSU for a conference, and it was literally a 13 minute walk to the conference location. Check in was easy, and Shan was very communicative.
The AirBnB is in a basement. You have to walk around the back of the house through a gate and then through the garage in order to access the room. It is well-furnished including a fridge, microwave, space heater, and private bathroom.
The only comment I would make is that the basement is not well soundproofed from the rest of the house, but the noise from the house is not loud.
