Jia's place was good for my needs--a comfortable bed and a clean room with wifi. Her place is very convenient to laundry and grocery stores. It's also positioned in a part of San Francisco that most travelers don't see too often, but it's great if you want to explore more residential areas and see how people really live. But if you need to go to other parts of SF, there are a couple bus lines and the Bart is a moderate walk away (the bus also takes you there).
