This may be quite outdated but the last time i stayed there, which was in January, they did not have the Heavenly Bed and Heavenly Bath. The room i was in was pretty old but it has a very high ceiling if that makes it any better. The service is okay, but then again, it is an airport hotel and so u hardly need to use their services.
I personally think that out of the three starwood properties at O'Hare, the Westin is by far the best.
