My wife and I just finished a 4 night stay at the Park Hyatt. Yes, the hotel is gorgeous, and the location is perfect, but this property is really defined by the quality of the staff. Courtesy and professionalism abound. Our room, 1305, had a breathtaking view of the Water Tower and Lake Michigan and was absolutely perfect and super quiet. The room was beautifully decorated and the bathroom was to die for. The restaurant and lounge are on the 7th floor and are upscale but friendly. The availability of a BMW 7 courtesy car was an added plus. In Chicago, this is where you want to stay.
