Hi guys/gals

I was hoping some of you Chicago people could give me some tips/pointers/advice regarding the Chicago area. I'll be attending Dental School next fall in Downers Grove and was hoping there would be some places to stay for the duration that aren't too far from the school but also not eye gouging expensive.

Can you guys recommend any housing areas and a little info regarding the area? (i.e. family area/ghetto etc...)
Also, this may be a little more difficult but, cost of living in that area. The latter is less important as I can always just look that up.

Thanks in advance
