IC Chicago
I just checked out of a four night stay at the IC Chicago. I usually stay at the Kimpton Gray but they were booked, and based on what I have read here and on FT I was expecting a disappointing stay.
It was actually pretty great. Yes, the hotel is older and the carpet is fraying, but I got a decent upgrade as a Plat AMB from the lowest category room to a 1 king premium city view room in the executive tower.
I was traveling alone so didn't need a suite, and the room was plenty large enough for me. The view was spectacular (see photo).
I liked the location better than the Gray, and the service was fantastic. Check in/out was super friendly, and then housekeeper was super sweet.
Maybe it's just my preference (I tend to like the classic hotels like the Willard, Barclay, etc) but next time I come to Chicago this will be my first IHG choice.
