Beautiful views of the Exploratorium, Alcatraz, and the Bay, beautiful mansions to look at, the edge of the foresty Presidio is right there, and (my personal favorite) the "Lyon Stairs." The Lyon Stairs go from Green to Vallejo and Vallejo to Broadway. They are beautifully maintained by the city, and they're also awesome to run up and down. There is a nighttime security guard at the stairs, and there are also surveillance cameras so crime is minimal. Parking is really easy here. It's fairly close (8 blocks) to restaurants/stores/etc. Also, since there are single family homes and few apartments (if any), noise and pedestrian traffic is minimal. It's very quiet.
