I stayed at the Sheraton Chicago Hotel and Towers in December of last year and had one of my worst hotel experiences ever. First, when I went to check in, I was completely ignored by the staff, they were rude and seemed to have better things to do than help me check in. When I got to my room, all the way on the 23rd floor, the room was dirty and had not been cleaned. So back down to the lobby and they seemed to feel it was no big deal and gave me another room. I went back to check and the new room was dirty also. There were pubic hairs on the bed and in the bathroom. It appeared the maid only went into the room and picked up trash and made the bed but did not clean. All I can say is YUCK! My next visit to the lobby the staff gave me an attitude about having to transfer me to another room AGAIN! Extremely poor customer service and gross rooms. I felt like I was staying at a $30 a night roach motel, not the $250 a night Sheraton. My advise is to stay away.

We just got back from 3 nights at the Sofitel. We really have nothing bad or negative to say about it. We've stayed at other higher end hotels in Chicago such as the Park Hyatt, The Peninsula, and The Four Seasons - and the Sofitel tops them all. It's a 4 star hotel with 3 star prices. It's a beautiful hotel all the way around. Staff is uniformly friendly without being patronizing. They were helpful with the one small problem we had and solved it quickly. The common areas are fresh and modern in appearance. The room was very clean with comfortable beds and well-appointed marble-accented baths. My wife loved the huge tub. We had breakfast via roomservice every morning and it was always hot and delicious. The robes and Evian at turndown was always appreciated. The property is ideally situated in the middle of the Gold Coast and all the best shopping and eating is within a short walk. Want a Bentley or latte? They're all close by. This was our second stay since it opened and I'm sure it's to be our home away from home when we are in Chicago.

My fiancee and I were looking for a modern, upscale venue for our wedding reception. We have found the perfect location at The James. From the ballroom to the personal attention to detail, each step was handled with care. Now that we have locked in our date, we are more excited than ever. Thank you staff at The James for making our day even more special!
