Beth's place and hospitality made my visit to San Fransisco much more fun, she was flexible and understanding in my check-in changes due to flight cancellation. The place couldn't have been any cleaner and hospitable. Transportation to downtown is super convienient as well.
Not to mention the special thoughtful touches, After a long flight I was happy to find that Beth was thoughtful enough to have a bottle of water and some snacks waiting for me in my room.
I guess that what Airbnb is about.
