It looks like you interviewed at a couple of schools who haven't gotten back to you yet. I would wait until you hear back from them, unless you are absolutely positive that you don't want to go to the schools you got accepted to, even if it means reapplying next year.
It depends where. In Manhattan, yes if you have a roommate or two or three. In any of the outer boroughs, definitely but you might need to do a bit of apartment hunting if you don't want a roommate.
I hate sharing a single bathroom with two roommates. They keep the bathroom clean and are pretty respectful, it's just that every time I REALLY need to use the bathroom, one of them takes a shower. Either they have the worst timing ever, or my body's waste removal system just likes to torture me .
For the record, we're all girls so these are NOT short showers.
I found this gem today:
