One of the most photographed locations in San Francisco, Alamo Square's famous "postcard row" at Hayes and Steiner Streets is indeed a visual treat. A tight, escalating formation of Victorian houses is back-dropped by downtown skyscrapers, providing a stunning contrast. The grassy square itself is an ideal midday break. One of 11 historic districts designated by the Department of City Planning, the area includes several bed and breakfast inns.
