We have traveled to San Francisco many times, but always on business...thereby staying usually close to the financial district or union square. We're thinking of staying down by the Wharf this time for pleasure...transportation to and from the wharf seemed always difficult, is it still? Should we stay closer to Nob Hill? We plan on going to North Beach and down to Pacific Seafood Café and take in Chinese New Year in between. Any suggestions. Budget between 170-250/night. no kids.
