Often visit Chicago, but this was my first stay at this location. Was able to secure a good rate through travelzoo. Thought the room was clean and was nicely decorated. Was very disappointed in the service. Stayed on a Saturday night - waited 20 minutes for extra pillows - called for 15 minutes but found out the third shift crew came in 20 minutes late. Also received an incorrect folio under my door(another guests that was staying at this location). I called the front dest to inform them of the error - and they explained that this was made in error and would be corrected. I opened my credit card statement and found that I was charged for three different rooms - one on the date of my visit and two a week later. I called the hotel and guest services took the information and forwarded to their accounting department. Received a message to call the billing department, have called three times - but have not received another reply back.

I enjoyed my stay at the Talbott Hotel. It is on the more expensive side, but it is all worth it. I got the Talbott tradition package, which was $245 for two people and included a $30 breakfast credit on check out day. The rooms are huge! The beds are soft and comfortable. They include Aveda bath products, which is a plus in my book. They also have a nice fitness area & pool you can use while you stay there. One thing I thought was really cool is that you can forward your messages from your hotel room phone to your cell phone. My boyfriend also liked the Ihome audio system. The location of this hotel is very convenient as well, its close to several great restaurants and blocks from the coast. But, what I like best about this hotel is that they make an honest effort to not negatively impact the environment more than they need to. They were one of the first hotels to be Green Sealed. Overall I had a great stay at Talbott Hotel!

I stayed at the intercontinental during the last weekend in September for a "pleasure trip" -- the InterContinental was in a great location and the staff was excellent. The room was clean and comfortable -- and came equipped with a new LG flat panel tv. Had breakfast at Zest (hotel restaurant) -- a bit pricey but decent if you want a buffet. The hotel is in walking distance to millenium park, museums and the aquarium. There is also a lot of shopping - window shopping is best though, considering the sales tax is 9.5%! (and possibly raising to 11%) Great stay. I highly recommend it and would stay there again.
