Q: The Sheraton Chicago Hotel and Towers is a magnificent grand hotel. The size of the rooms, and the views of the city are phenomenal. At night the city lights up, and the sight is majestic. The hotel itself, and the employee's are wonderful, and well worth the pay to stay in such a place. This Hotel has so much to offer, great dining,a fantastic gym set up for those of us, who really like to stay fit no matter what we are doing.My wife and I have just left recently, and we are already planning to stay there on our next trip out. Big thumbs up to Those who run that place, and helped us enjoy our stay.

A: positive

Q: The Conrad Chicago hotel had some of the worst service I have ever dealt with. I got the Executive Room with a king size bed. When I got in, the sheets were stained with some type of chocolate or mud. I called down to front desk and it took them an hour to come up and change them for me. They have a pillow menu which I tried to select from but they were out of over half of them. The Ipod dock was not working either. Also, the room service servers were very short with me and delivered my food luke warm. This hotel is the worst in Chicago and I would never recommend going there!

A: negative

Q: We wanted a nice place to stay the night after dinner, theater, and my daughter's 21st birthday. This place certainly fit the bill. It was convenient to everything including the SouthShore Railroad station. The staff were all friendly. Their was a small wine reception in the lobby in the evening and Starbucks coffee in the morning. Ryan, the concierge, ordered flowers for my daughter and had a nice bowl of Hershey Kisses waiting for us when we arrived. We were upgraded to a suite and although they forgot to make up the sofa bed, they came promptly to get it set up when we called later. The window seats were beautiful as well and I enjoyed drinking my coffee in the morning and reading a book.
