The hotel was located within walking distance of most of the "touristy" places we wanted to see. Walking distance to so many great restaurants, the staff was so helpful with restaurant recommendations and everyone we encountered were so friendly. The breakfast buffet was reasonable priced and the food was good.

Great spot for our Chicago weekend. Lovely staff, location our room…Husband was concerned about the shallow’ish pool but ended up loving it for swimming laps each morning. On-site parking made our trip stress free and was worth every penny. Thank You AC Hotels for another great get away.

Staff was amazing and friendly. Room could have been cleaned better. Old bar of soap was left in the shower. The Netflix in the TV would load and the iron didn’t work. The rest of the room was clean and bed was comfortable.
