"gorgeous upscale area"
W Clay Street is in a very nice residential section of SF known as Sea Cliff. The homes here are immaculate and large but very pricey. If you are lucky enough to be able to live here, it is a very quiet area, with beautiful homes that actually have small yards, which are well manicured. W Clay is near Lincoln Park, Presidio, and Golden Gate Bridge. If you are commuting to Sausalito/Marin City for some reason this is a good location. It is far from downtown SF, but is such a beautiful, quiet, and desirable area that it is worth a commute.
