Only hotel I've ever left 2 hours after checking in.
I should have known when I pulled up to the Allerton and no one greeted us that this would turn out bad. I waited 10 minutes for someone to valet the car. No bellhop service, so we hauled everything up ourselves. 
The front desk staff was friendly. 
Walking off the elevator on the 20th floor, the carpet was worn and stained. The walls were beat up, and the patch jobs on the wallpaper looked like a 2nd grader repaired it. 
Getting to our room, it's nowhere near as big as the pictures online showed. The shower had soap scum on the walls, the grout was dirty, and the sinks hadn't been cleaned out. Our linens hadn't been changed as evidence of the hair and stain on the sheets. 
The staff did try to get us in a different room, actually much bigger, but the overall experience made us wonder the cleanliness of the hotel cleaning staff. Wouldn't go back here again especially since there are much newer/cleaner hotels for just $20 more a night a couple blocks away.
