As in the best cities, an entire life wouldn’t be enough to see every little corner, every house, every garden in San Francisco. One of my favorite thing is to stop by hidden little gardens.
This one is in Hayes Valley, the uber-bobo hood.
The more romantic might be Macondray lane, even if it is in most of the tourist guides, I’ve never seen a lot of people wandering there. It has inspired the Tales of the City saga which were happening right there! (see below how steep are the stairs).
