my judgement on the Hilton SF is not so far away from philforest - a caserne, to big, to unpersonal. When I wake up I have no San Francisco feeling at all. If you can afford it: Ritz, Sherman House, Mandarin; only one class less: Mark Hopkins (InterConti) with the sighseeing top of the Mark bar, the Renaissance Stanford Court, the Clift (and a really cheap outsider tip: the Atherton (60 Dollars).
