I love visiting Land's End early in the morning when the light is new and the city is waking up. There's a spectacular view of the bridge and the north bay. Makes me grateful to live in San Francisco.
Located near to the Alamo square's Painted Ladies is this wonderful gothic "stick" Italian villa with a long weirde history. Built by a Candy Baron in 1889, it's housed variously; a Russian Czarist nightclub, Jazz musicians, Satanists, a Manson family member, and one of the first 60's Hippy communes -Calliope. Creepy as hell enshrouded in fog after dark.
#1 in the city for old book smell and creaky wooden floors. Too small to find anything specific you’re looking for, good enough that you’ll find something else instead.
