I stayed at the millennium Knickerbocker for 3 nights while on a business trip, as it was conveniently located a few blocks away from the office I was visiting, and just about everything else for that matter. The lobby was absolutely beautiful, and the staff was beyond courteous and extremely helpful. The rooms were elegant and spacious, and I instantly felt right at home. The large flat screen TV as a nice touch and TV options were many. I headed downstairs to the bar for a drink, and was amazed at how well kept it was, as well as how nice everybody was. As this was my first time I asked the bartender about the area around and he gave me great advice about some places to check out. All in all this was a great experience, and next time I'm in the area, I will definitely be staying here. I'd recommend the Millennium Knickerbocker to anyone traveling to Chicago.

Whilst no doubt being in a good location this hotel falls short in other areas. Most notably is cleanliness, as although the lobby was very clean, the corridors of my floor as well as the room was not. Dust lined the carpeted floor for the hallways, and in the room the the bed emitted an unpleasant odor as if the sheets had not been changed in some time. The furnishings were nice and modern, but with various blemishes upon close inspection. Bathroom was relatively clean, with the exception of the shower. View was nice for this particular room, and service was relatively quick. The food in the restaurant was average but again cleanliness was an issue. This time with the glasses which were stained, the waiter promptly apologized and returned with new glasses but this is still inexcusable in what is advertised as a high class hotel. I will not make the mistake of staying here again.

We paid $75 a night through Priceline, which is excellent for June. Our room had a fantastic view of the Hancock Building and the river. The room was large, clean and had a couch, easy chair and desk chair. The bedding was the newer 'non-bedspread' style, the bed was comfortable, the bathroom was large and, well, we were pleased with the room and the Hyatt in every way. We ate at the lobby restaurant, which is attractively decorated and was bustling with activity when we were there. We only got Cobb Salads, so I don't know if the food, in general, is good or not. The Cobb was so-so. Our only complaint was the $48 fee to park your car over-night and the $13 daily fee for the internet. Many places are offering free internet these days and I wish the Hyatt would hop on board with this concept. We hated to leave!
