We took a three hour tour with Caio and Miss Daisy (the VW bus). He was a great tour guide, very knowledgeable and willing to show you what you want to see. Among the places we saw were: Nob Hill, the Civic Center, Twin Peaks, Haight-ashbury, the Painted Ladies, Full House, Lombard Street, Pacific Heights, Billionaires Row, the Presidio, Crissy Field, Coit Tower, The Palace of Fine Art and China Town. He also recommend a great Chinese restaurant for us to eat at. Highly recommend Caio to anyone touring San Francisco.
