Truth about iit?

I recently asked someone about iit chicago and this is what they said, "I would suggest go for other universities. I went to IIT Chicago, business school is in downtown. Don’t even imagine you going to main campus. We don’t have anything there. And business school is in a building downtown. That’s it nothing interesting in that building. IIT Chicago impossible to get a GRA (graduate research assistant)OR TA (teaching assistant ). And I would suggest go for some public university than private. You will have lot of fun and events in public. I still regret joining private. Wasted my money". Is this correct and if yes what are the other insights about iit chicago one should know before applying.
