Hotel Sax
Just got back from a one night stay in Chicago. Found out about Hotel Sax onTravel Zoo. The deal went through fine. $149 a night versus $269. The lobby floor plan was very strange. Huge bar but very little space to gather or sit in lobby. Once in our room, we could not find ANY switches for the light except at the door and in the bath. Tried to call the desk and once we found phone couldn't figure out how to use without the lights. Turns out switch was on each VERY flimsy lamp that was hard to see or find without the light. Should have brought our flashlights! 
Location was good for our purposes. We were able to use public transportation easily. Concierge and bellguys were very friendly and helpful. 
And the bed was luscious with great linens. I was easily able to forget that the bottom mattress was left exposed. (Maybe that was part of their decor). 
And the air conditioning worked!
