The horrible smell may distract you from the rude staff...
... but I wouldn't count on it. My room, my hallway, the elevators- all were saturated with the smell of musty dirt and cigarrette butts (my clothes still smell). But even that was an improvement over the parking garage with its almost unbearable urine reek. I was afraid to leave my car there for fear someone would use it as a commode!
I was forced to sign a "non-smoking statement" for my non-smoking room, which is unconventional and a bit insulting, but I figured "Hey, whatever works...". The problem is that it doesn't work, at all: the statements obviously are poorly enforced because there were butts in the hallway and my room smelled awful. The bedding was all smoky and the towels were too. Oh, and there was dirt on the floor, especially in the hallway, where I hesitated to put my bag down lest it come away contaminated.
And yet, with all that foulness, it was the unfriendly, unsmiling, unhelpful attendants at the front desk that really wrecked this place for me. They didn't even make eye contact with me- I felt like an inconvenience to them and like an idiot for staying in this place. I spoke to another staff member that I met in the elevator, and he laughed about my issues with the room, saying "a lot of the hotels down here are like that". I am willing to take that chance in the future. 
There is no way that I will ever return to the Crowne Plaza. The sidewalk out front is cleaner than the carpet inside. The dumpsters out back probably smell better than the rooms. I have literally, seriously had a better customer service experience receiving a traffic ticket than the one I had at the front desk. 
I do feel bad giving horrible reviews, but you know what? This hotel and its staff made me feel bad, very bad. Turn about is fair play, I suppose.
Avoid this place at all costs.
Cheers and safe travels.
