The Roosevelt Hotel is at 45th and Madison, ~3 blocks away from your venue, and in that range. It's fairly nice - rooms are small, but clean and sufficient. I've gotten priceline bookings there a couple of times which turned out to be a good deal. In general, if you're not too picky, I'd suggest trying priceline (being sure to select a 3 or 4-star place and specifying the location precisely.)
