I want everyone to know about the awful experience I had at the Sheraton Chicago Hotel and Towers. When we arrived at the hotel, the clerk who was checking us in said that our reservation was not in the system (I had called earlier in the day and confirmed it). After speaking to the on-duty manager we were informed that our reservation had been canceled earlier in the day and that the hotel was now completely booked. We later found out that there was a convention at the hotel and that the price for the rooms had risen dramatically. I believe they canceled our reservation just so they could make more money. I for one won't be going back to this hotel!

Great, awesome service. Seriously, the people are amazing. That, and the nice bartender who serves after last call (at least, that's what I was told - I of course don't drink) save this place from one star. But seriously blah, small, non-luxury rooms with beds that are just really uncomfortable - and for a card rate of $725/night, even in a major city, the rooms better be awesome. I've had waaaay better rooms in NYC for $350/night. (Good thing I had a corporate rate.) And my room was not especially big, despite what the below reviews say. But here's the main problem. Even on the 10th floor, the guy blowing the whistle to summon cabs downstairs woke me up at 6, and 6:15, and 6:30, and 6:45, and 6:50, and 6:55, and...and, well, I finally got up and said screw it, let's greet the day. Maybe everyone else was already up, but somehow I doubt it. Am now safely ensconced in the Four Seasons.

We stayed here through Hotwire and got an amazingly low rate- $60 some odd dollars nightly for a 2 night stay last May. The room they had us in was small and had no view of anything except the wall of the other part of the hotel, but it was very clean, tastefully decorated and cozy. We had a great vacation, walking all over town until we ended up near the Planetarium which was where we then turned around and saw the skyline of Chicago and were just wow. So anyway, the hotel is great, the service was great, the room was very nice- I would recommend this hotel to anyone though I work at the front desk of a hotel myself and the previous person's comment about how she wasn't able to get adjoining rooms, well, internet sites don't guarantee things like that anyway- you've got to call the hotel direct and verify things like that. There's a note about that on internet sites as well- no room type/location is guaranteed. 5 stars out of 5 for this hotel.
