Get off the bus at the corner of Lombard Street, just before the Embarcadero. The entrance is through the brick building half way up the block on your right. For a cultural and unique experience take the F car on Market. The city bought a small fleet of 72 year old streetcars from Milan that provide a charming ride from Market on up the Embarcadero. Walk up the west side of the Embarcadero past Battery Street and turn left onto Lombard.
Entrance is mid-block on the left hand side.
There are several options. There is metered parking on the street.
