No air conditioning! They have a fan in each room (that you can barely feel) but no AC at all. On the 13th (creepy) floor too. We stayed here in April, couldn't imagine staying during summer months with no AC. Found out after the stay that this is "the most haunted hotel in Illinois" (google that)....I don't believe in ghosts but its such a creepy place, yikes. The only + is location, it's in an excellent location which must be why it still exists.
