This was my second visit to San Francisco and I wanted to explore the genuine part of the city away from the touristic part, but easily accessible from the airport. Chan's place filled it's purpose very well. It's in the middle of Mission, a few blocks from BART and a bus stop right outside the door, if you want to go downtown.
The apartment is quite dart, but it didn't matter as I was out all day.
Chan is a very nice and generous host.
