Bad for the brand
We arrived and thought the location was great and checked in with pleasant front desk staff. We were also happy to have a Starbucks in the lobby. Our stay went downhill from there. We got to our room - it was a mix of dark yellow walls, maroon velvet couch, old curtains coming off the rails in some parts that let a lot of light in while trying to sleep. Old peeling wallpaper in the bathroom, old carpet, broken lamp, an engineering power bar sitting in the middle of the floor. These are all things my husband and I just rolled our eyes at, not real problems, just trying to give you a picture of our room.
These are the issues we had with this hotel:
-Extremely loud and inefficient heating/cooling system
-TV didn't work, maintenance was willing to try and fix it but at this point we had already gotten in to bed and didn't want them in our room
-They charge for Internet 
-They charge $12.00 to use the fitness center, which is only equipped with cardio equipment
-*******The windows were being cleaned and there was no notice of this sent to us, all of a sudden there was window cleaners banging our windows staring straight into our room. Letting us know to keep our curtains drawn would have been a good idea.*******
-*******We had the "Do Not Disturb" sign on our door. Despite this sign the cleaning lady knocked, then proceeded to try and open our door only to make a huge bang against the security lock, then realizing we really meant "Do Not Disturb" left a note saying she tried to clean our room. Then a few minutes after this CALLED our room and left a message saying she tried to clean it! All of this while we were trying to sleep with our "Do Not Disturb" sign on the door.*******
The best part of our stay here was the quick and easy checkout. 
We actually had the Intercontinental booked in Hong Kong for later this week but cancelled and booked a different hotel due to our stay in Chicago. We will NEVER stay at another intercontinental again, they've lost us.
