We usually stay at the Sofitel but thought we would try the Conrad for a change. I don't think I would rate this hotel over the Sofitel but it was still 1st class. But I do think the service was better at the Conrad. We arrived at the hotel just before the restaurant closed and soon we were the only table left. Normally service goes down hill then but our waiter Eric was the best. Even when I kept ordering my after dinner ports. The meal may not have been The Chop House but it was still very good. The bar was ok, no Crown Reserve. They did have the Cask 16 at $24 a drink, ouch. The room service was very quick. Our room was very clean and the maids replace everything including the ashtrays during their visits. The only fault we could find was the temperature on the 14th floor. It was so hot that we had our window open the whole time with the heat turned completely off. Which wasn't so bad since my wife smokes. The temp on the 5th where the lobby, bar, and restaurant was fine. We enjoyed the hotel enough that we will be back in Sept. One last thing, if you like a cheap fantastic breakfast. Go to the West Egg, only a few blocks away.

The Hyatt Regency Chicago hotel is perfecty located in the center of downtown Chicago. Whether you are going there for business or pleasure, it is in the perfect place. The rooms are large and beautiful and the ball room took my breath away. The wi-fi connection was perfect for the work I needed to do and the show at the Navy Pier was perfect for when I needed a break. Other hotels have nothing on the Hyatt. I just wish there was a Hyatt Regency in every city for all of my business trips.

My family of four went to a convention and stayed here in early August. We were promised a room with two double beds. When we arrived (earlier than most) we were told they were 45 double beds short. We reluctantly agreed to take a room with a king bed and a promise of a roll away bed. We had a to sleep very uncomfortably with a 12 year old in our bed and our other child in the roll away. Little did we know we were being CHARGED a daily fee for this bed. The managment could not handle the large group that was at this hotel. The bellhops and bartenders were visibly stressed and we did not have towels one day until very late at night. The managers would not take off the roll away bed charge and were not the least bit accomodating. We were so disappointed in this hotel. Also, they do not have a pool here. If you want to use a pool there is a health club next to the hotel but you have to pay $20 a day to use it. $80 for a family to take a little swim was a bit ridiculous. Do yourself a favor, if you want to be accomodated and are thinking of booking this hotel for a convention or otherwise, go elsewhere. Chicago has too many hotels to choose from to pick this one. I never heard back from managment on this issue when I called and emailed so obviously they don't care, even when I told them I'd write a review on this website. Chicago is an awesome city though. We loved it!
