We stayed at the beautiful Millennium Knickerbocker Hotel located in scenic downtown Chicago. It was close to shopping, local attractions like the Shedd Aquarium and even the Navy Pier. The hotels featured luxurious amenities like a ball room and in room massages, which I took advantage of as any woman (or man) should! A continental breakfast is available for a nominal fee, unless purchased with a package deal, in their own upscale restaurant, Nix! We would definitely book a suite there again and highly recommend this hotel to all our friends and family!

After reading good reviews about I booked a 5 night stay. Checked in late bit called early in the day to assure we'd have a roll away as well as the pull out sofa for 2 teens. They somehow had us booked for two rooms instead. Got that sorted out and arrived around 10 pm. Checked in and waited for our luggage... Finally went down and got it ourselves. The room was a little grungy, furniture shabby, and discovered a suspicious stain on the duvet cover. Ewww. Called for a new duvet cover which was delivered and unceremoniously handed to me. FYI it's kinda gross to have to change the duvet cover in a hotel. Next day tried to iron a dress for dinner and the iron didn't work. Called for a replacement, waited a while, called again and was brought another iron which also didn't work. Third time was a charm. Oh boy. Too bad we paid in advance. Won't be staying here again.

We really enjoyed our stay at the Palmer House Hilton. We were in Chicago for a weekend stay, and wanted something close to State Street, and convenient to the theatre district and the museums, and Michigan Ave. shopping. This is a grand old hotel, with just about every amenity one could wish for. The lobby is fabulous, and the hotel also has some nice restaurants . Our room had a nice king sized bed, and was pretty cozy. Hotel employees were very nice and helpful to us. I would definitely recommend this hotel if you want a "grand hotel" type experience at a reasonable price for the many amenities and in a very convenient spot in downtown Chicago. You will definitely feel special.
