You might want to utilize a student host, unless you've got a significant other that you're bringing along with you. There's information about hosts in the interview e-mail that was sent.
I grew up in the area, and I can tell you that you're not going to find a really nice place beyond a motel. Otherwise, you can look into a place near one of the airports (like if you're flying into LGA). There are city and express buses that run into the Bx.
Best of luck. I might see you next month, depending on when your interview is scheduled.
I stayed with a student and highly recomend that. He was cool and lived right across the street from where the interviews were. I dont remember seeing any hotes within walking distance. Also, its about a 30-40 dollar cab ride both ways.
