San Francisco does seem pretty friendly and pleasant, whenever I picture it I think of Danny Tanner's smiling face and the opening credits of Full House, so it gives me happy feelings. I would like living there too!

It's probably more expensive than Manhattan over all because it seems (I have no clue) like it's all an overall pretty nice area, while some parts of Manhattan are insanely ritzy and nice (Upper East Side right by Central Park, where my singing teacher's singing coach lives~ <3), but then some parts can be pretty ghetto.
