I recently stayed at the Hard Rock Hotel in Chicago while in town for business, and enjoyed my stay very much. I stayed in a room with a king bed, which was very comfortable. The room had all the things I needed for my stay, which was nice. The only thing is I think there was a party on my floor, but they quieted down quickly enough. My room even had an internet connection! I also had dinner one night at the China Grill, and it was an amazing meal! Overall, I had a great stay, and will return next time I am in Chicago.

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.

My wife and I decided to spend three days in Chicago last summer, and booked via Expedia. When we first walked into the lobby we almost fell over at its' beauty. It's like something out of Europe. We were able to get a free room upgrade, even though the rooms are still a bit small, but its' an old hotel in an old city. It's there for sleeping and showering. The restaurants, lounges, and shops were all wonderfull. The next time we travel to Chicago, I'll be affraid to stay anywhere other than the Palmer House Hilton
