Superb location "in the loop"
Lovely, historic hotel right downtown, within the loop. Walking distance to all the downtown attractions: Millenium Park, Willis Tower(Sears), Boat Cruises, State Street Shopping, Magnificent Mile. Hop on, Hop off bus and subway. 
We booked through Hotwire and got an amazing deal. I was also able to call the hotel on the day of our arrival and upgrade our room from a King to 2 doubles. We were also offered an upgrade to the executive suite with extras as listed in a previous review for a reasonable price but this was a budget vacation so we passed but I do think it was a good deal. We were on the 16th floor overlooking a roof and alley but although the view was lacking, this made the room quiet and we heard no street noise. We were also in the corner so heard no noise from the hallway either. 
Comfortable beds and Hilton quality bedding, towels and toiletries. Comfy pillows. The room was small but there was room to put an armchair if they wanted and that would have been nice. 
Great shower pressure, good closet space and room thermostats that worked very well and quietly. 
My main complaint was lack of a coffee maker. I haven't stayed in a hotel in the past few years that hasn't had a coffee maker. The Starbucks closes early and even McDonalds down the block closes at 11. 
We ate at the restaurant and although expensive, the service and food were excellent. The noise from the bar was a little disturbing though. This meal was our one splurge of the vacation and it was worth it. 
There are plenty of reasonably priced restaurants in the area. 
Overall, great location, comfortable, clean hotel.
