I'll be joining in your inquiry, only-time. I couldn't go to the on-campus interview either so I did phone interviews this weekend. I dunno when the decisions will be out, but I'm seriously considering Mt. Sinai.
I think I could answer the life and neighborhood portion of your questions, though. I have been to New York City in the past, and if you are not used to the big city life then you'll have some major adjusting to do. The school is in the Upper East Side, so there's some really good cultural places (e.g. museums) around, and everything else is basically a stone's throw due to the metro system.
I also believe they offer housing near the school campus, but I dunno how cheap that is compared to, I guess, living across the bridge in Brooklyn or NJ.
