Absolutely Inexcusably Bad
Before i start my rants about this cesspool of a hotel let me start by saying that each and every front desk agent i dealt with was friendly, professional and personable which is truly amazing considering the dilapidated hotel they have to deal with on a daily basis.
I was assigned a room with two double beds on the third floor. The lobby area looks respectable as does the bar area. The walk to my room was probably a city block. 
Upon entering the room i saw what i can unquestionably say is the worst hotel room i have ever seen in my life (and i've stayed at some pretty cheap places when i was in college). The room smelled awful, the carpet was full of nasty stains including a two feet by two feet patch of bright red stain right in the middle of the room. How does housekeeping not see this, notify management and have this room put out of service? The sleep number beds were squeeky and at least one of the remotes to control them did not work. No flat screen to be found in this room. The tv in this room was probably hard pressed to be considered modern in 1985. The bathroom continued this trend with a toilet with a huge crack in the bowl and a shower covered with mold and mildew complimented with the stopper just sitting loose in the middle of the tub. 
There was no way i was about to stay in a room as filthy and disgusting as that one so i went back to the front desk and explained that crawling into a sleeping bag at the city dump would be preferable to the assigned room. The very nice agent apologized and moved me to another room in the tower section. The new room was still very old but noticably more attractive with newer carpeting. This room still sported pealing wallpaper and a cheaply installed plastic shower liner that needed to be regrouted. The AC unit in this second room was not working and had a flashing error code displayed. After reporting this to the front desk i was informed that maintenance had gone home for the night. I weighed my options and chose to roast like a turkey as opposed to risking yet another room. A hotel in this condition needs a staff of probably 20 maintenance people working around the clock to even make a dent in the problems this hotel has. 
This Radisson is a absolute and complete disgrace to the chain. Not only does Carlson need to pull the franchise on this dump but the city health department should probably have a look at this place as well.
