I just finished a four night stay here, and liked it. The hotel had the modern feel of the other city Conrads I've stayed at before.
The room although we were not upgraded, was fine for two people. They did make an effort to upgrade us but sadly no luck. But as bonus they threw me a few extra points and free drink tickets (sorry no exec lounge here).
The bathroom was good sized almost bigger then mine at home, quite surprising for a city hotel. Only thing I really missed was the Nspresso machines like in the Maldives or Dublin

.
I'd for sure stay here again on my next trip to Chicago. If you'd like to see a full review and tons of pictures
