I really wish I could say that I liked this hotel, but the whole experience was just plain awful. My first warning sign should have been when I made my reservation. The person I spoke with when placing my reservation had absolutely no idea what he was doing. At first he tried to book me into the wrong hotel, and then when we finally got it sorted which hotel I was actually wanting, he booked me for the wrong dates. He read me the right dates, and it was only when I called back two days later to confirm that I found out he'd given me the wrong dates. Hilton did get it fixed, but I already had a bad feeling about my stay. Then came actually staying at the hotel. The people at the check-in desk were downright rude. Then there was the room. I was supposed to be in a non-smoking room, but the room smelled strongly of cigarette smoke. The hotel staff refused to believe me, but did let me change rooms to one that didn't smell of cigarettes. However, I might as well have stayed in the first room. I was short towels, and it took four calls(over a period of 12 hours) to the front desk to get some. The sheets had not been changed, made obvious by the crumbs and fresh stains that littered them. Yes, I was able to get fresh sheets, but like the towels, it took several hours for them to be delivered. Since this is a pet friendly hotel, lucky me I got stuck in the room next to the room filled with yappy little dogs. The walls were so paper thin, all I could hear all night was barking. When I complained about it, the staff refused to believe me, and said that the walls of the room are so thick I shouldn't be able to hear anything from next door. Yeah right. I was excited to use the pool, but just like my room, it hadn't been cleaned recently. Then, I tried the fitness center. Half the equipment was broken. I tried to cut my stay short, but of course this hotel wouldn't work with me at all. They even refused to comp my stay for all the grossness I had to deal with. I will never stay with Hilton again, and I will be sure to let everyone know what a nightmare this stay was.

As a frequent traveler for work, I stay at many SPG properties. Compared to all the SPG property in Chicago, this is by far the worst. Why? 1) They charge you to use the gym. $12 per day or something like $24 for your entire stay. I can't even begin on what a rip off that is. 2) As a Gold or Platinum member, you always get a complimentary water bottle in your room. They do not offer that option here and you have to make a fuss about it before they give you one. 3) They do not have wireless internet. It is 2010- enough said. To charge you at least over $200 a night, all the above amenities should be built into that cost. I would never stay here again.

I have stayed in hotels all over the world, and this is probably the worst service that I've ever experienced. The staff was unaccomodating and the hotel did not provide the services that it claimed it would. I decided to try the Monaco because it seemed interesting, was close to the theater, and had what seemed to be a good rate. What a huge mistake. The front desk staff was condescending and not even remotely helpful. The room was not clean, the gold fish we had requested came many hours after we told them we would be arriving, they never bothered to come turn down the beds, and the late check-out "priviledges" which were guarenteed when I booked the room suddenly became "upon request" - boy the extra 30 minutes they gave me sure were helpful. Dont' waste your time or your money here. At best, it's nothing special. Personally, I like the Fairmont in Chicago, but anyplace woudl be better than the Monaco.
