Vivian was a very nice host. My friend and I arrived an hour early and she was willing to accommodate the check-in time. The apartment has one queen-size bed and a full sleeper sofa and enough space for us. It was clean and comfortable!
The location of the apartment was great. It is half blocks away from bus 38 which takes us to the Union Square, Japanese Center etc, and a few blocks away from the Golden Gate Park. There are some nice restaurants in the area.
Overall, I would recommend Vivian's apartment to friends and would stay there again.
