The best way to get to the hotel in this compact city is to catch the Bay Area Rapid Transit (BART) from either the San Franciso or Oakland Airports.
Get off Bart at the Powell Street Station, ride the escalator to street level and catch the Powell Street Cable car to California.
From Oakland Airport one way fare is only $6.70.
One could also catch a taxi at Powell as there is a good possibility of long lines waiting to catch the cable car.
