Great Hotel!
We enjoyed everything about the Doubletree, it is our brand of choice. Great location, close enough to walk to Navy Pier and Milennium Park. The walk to the subway is a little far but not too bad, I wouldn't want to do it with luggage though. Beds were comfy, room was large, and bathrooms were clean. The mini-bar is pretty pricey and has sensors on it so if you move anything you will be charged for it. But there is a 7-11 convenience store within a block with all the snacks and drinks you could need. There was also a business center that you can use for free with free printing as well. When we come back to Chicago we will definitely stay here again.
