I spent a week at Cornell in December when I interviewed at Columbia, and I just don't get how people say Cornell is in a much nicer area than Columbia. Both Cornell and Columbia are surrounded by big buildings that will be your scenery on the way to the Subway. The schools are within big buildings, and the hospitals are big buildings. It's city life either way - not a whole lot of difference. The three things that put the location of Cornell over Columbia (for me) is 1. in midtown and closer to downtown (for night life purposes), and 2. greater variety of bars and restaraunts directly surrounding the buildings, and 3. subsidized student housing. I know the perception of safety is a fear for some people at Colubmia, but I never felt unsafe walking around the campus - maybe I didn't venture far enough away? Either way, both schools are fantastic, and I would choose between the schools based primarily on curriculum and any financial aid offers, leaving location a distant third (or fourth, or fifth...).
