I just went to their website and looked at the pictures, the room is pretty standard, but the pool looked nice. It was small, but it was lakeside, which I thought was nice. The breakfast area looked fine as well.
We actually stayed at a Comfort Suites once, the room was clean, but older, but again, like you, got a great rate.
I think you will be fine, don't sweat it. There are far more expensive hotels with worse problems. It always make me laugh when I read how some people have to bring Lysol with them to the Polynesian at Disney because of the smell.
Don't worry about it and have fun, and think of all the money you saved!
