Great Location - Elegant w/o Being Pretentious
My husband and I recently (July 2012) stayed at the Conrad Hilton in Chicago for a work trip but also to celebrate my birthday. The location to the downtown area and Michigan Avenue was perfect. The hotel is connected to a mall and you can easily pop out onto Michigan Ave. using this connection. We also walked to Navy Pier from the hotel.
The bed was extremely comfortable and the bathroom was enormous! The staff at this hotel were great from the check in staff to the bar staff. They have a great terrace that you can sit and enjoy a drink or a meal. We didn't eat at the hotel restaurants simply because there is so much right around this area. 
I especially enjoyed the vibe of this hotel. It is elegant and well appointed without being over the top or pretentious. You can walk through the lobby in shorts and flip flops and not feel out of place.
Great hotel experience overall!
