I lived in NYC East 34th for many years. Later I moved to SF. I was very surprised that SF is not a city like New Yorkers think of cities. Yes, the SF people are nicer, but also snootier. I strongly recommend a scouting trip to find an area where you are most comfortable. It took a while, but I found just north of the ball park to be the best NYCish for me. But, remember, SF does not work like NYC.
