Great place
I recently went to Chicago for some computer training and this Hotel was used and recommended by the training vendor. I found it to be great and had no issues. It was close to OHaire airport and the shuttle picked us up. There seemed to be a little confusion as there are several Holiday Inn shuttles. The training room was comfortable and we had a buffet dinner and lunch there and the food was wonderful Couldn't have asked for anything better. It was so nice to have everything provided on site and the banquet staff was extremely helpful. They had a bar and restaurant at this facility and again we had breakfast there one morning and drinks there one night and I found it to be satisfactory. The rooms were cozy, the air conditioning worked great, but my roommate froze and there was little to cover up with. A very light comfort was on the bed. 
We wanted to use the pool, but it was being renovated and apparently has been under construction for a while. It would have nice if they advised us of this factor at the time of reservation. We were told it was within walking distance of alot of things, but I didn't see much within walking distance. We were close to the metro and decided that take that downtown. Which proved to be a 20-30 minute ride. The front desk, was very NOT helpful with directions or recommendations. I was disappointed with that and they didn't seem to know some basic info about whether we were to receive food vouchers with our group. I overall had a great experience and would not hesitate to return to this facility. Again I found it to be a great meeting place, and slept as well while there.
