Yes taxation is high in San Francisco. Politicians love new revenue sources. Especially a small group whom they can vilify and tax.
If you are clever, you can monetize extra services. It's hard work to make it palatable and seemingly value added. I think the easiest way is to make two listings - one bareboned, they other luxury.

Airbnb has an anti-tipping policy. (They say a personal note is the best tip!)
Airbnb's anti-tipping policy is the only reason I would ever seek a competitor.
