Q: I stayed at the Omni for one night following a business meeting at another downtown Chicago hotel. I was completely impressed by the service; all personnel during my stay were absolutely outstanding. I checked in quite early (no problem) and was efficiently checked in. My room had a somewhat heavy scent of air freshener (the ONLY negative from the entire stay), which was managed reasonably well by opening the windows. I don't generally require much during my hotel stays, but suffice to say the doorman, housekeeping, the night manager and bartender at 676, the day waiter at 676, and the concierge were amazing - I never waited more than about 30 seconds for anything. The room was very comfy and the amenities were superior. One very tiny complaint - there was no wastebasket near the sink or near the wet bar - had to walk to the other end of the bathroom or sitting room to dispose of kleenex/coffee paraphernalia. One wastebasket would make all the difference. All that said - what a great hotel!! Thanks, Omni - I had a great stay!

A: positive

Q: When I was asked to stay at the Swissotel in Chicago, I immediately went to their website to check them out. What I found there was decent, nothing really stood out. It wasn't until I actually went there that my eyes were opened. The amazing customer service I received there was exceptional. Every whim and detail I asked for they helped me perfectly. The room was neatly fixed when I arrived and was cleaned every day. When I asked about more towels, the maids were happy to help me out. If I were ever to be in that area again, I know exactly where I'm staying, the Swissotel.

A: positive

Q: Overpriced is the best word to describe the Conrad Chicago hotel. While it may be in downtown Chicago, the room had no view. Although I asked for non-smoking, the room reeked of smoke. The elevators were very slow, and one was not working during my stay. There was a stain on the pillow, and the leg of one of the chairs in the room was broken. There was a dead bug in the bath tub. I was only given 2 towels for my 4 night stay. My credit card was billed twice, and it took 2 weeks to reverse to extra charge. I do not recommend this hotel at all!
