Joan is such a great lady. She is really friendly and warm. It's easy to immediately feel at home. The room is nice and spacious, with a super comfy bed. It's also nice that you have your own bathroom when staying here.
If you're trying to go into San Francisco's downtown area a lot during your stay, it's definitely a process. Typically a 20-minute walk to the nearest Bart and at night catching a cab was usually the best move.
I didn't get a chance to explore Oakland, but it seemed like the neighborhood had a lot to offer!
