Long time Thumbs listener and forum lurker but first time posting. I'm graduating from school in Los Angeles and moving to San Francisco this summer for a job in the Financial District. I want to be walking distance from work which leaves only Nob Hill/Russian Hill/North Beach as my choices. I'm from Northern California originally and know the area pretty well, but had no idea it was this difficult to find housing in the city. Anyone local have any advice besides just craigslist?
