Hilton San Francisco Airport Bayfront.

The Hilton SFO Bayfront offers non-guest parking effectively through the adjacent Burlingame Airport Parking (BAP) lot at ~$10-15/day. Direct rate at the hotel is $40/day — use BAP or SpotHero for the cheaper rate.

Shuttle is operated by Gateway Global, shared with BAP. Runs every 10-15 minutes but reliability is frequently criticized in reviews. Located on Airport Blvd in Burlingame.
