Yes, per bedroom per month. It's more like $1800-2400 for a 3br though, because those appear to be the most cost-efficient. Off the top of my head, I remember visiting one place that was a 2br for $900/person (including utilities) around 140th which I liked, as it was quite spacious, but it was a bit out of my price range. IMO, if I had $1100/month or so I could have found a place in a great 2br pretty easily though. Quality seems to vastly improve with each additional $200/month.

Oddly, Brooklyn and Queens were not cheaper.
