We stayed at the Amalfi Hotel for our trip in July 2010. We really enjoyed our stay and highly recommend this location.
Location: Walking distance to most attractions: downtown, cloud gate, and the loop
Room Service/Customer: great clean rooms, concierge answered any questions we had and offered suggestions for great restaurants and sites to see.
What we enjoyed the most was the nice little touches that you don't get with the big chains such as the free wi-fi in the room, continental breakfast (which included fruits, pastry, yogurt and drinks) and complimentary happy hour from 530-7.
I would definitely return to the Amalfi the next time I'm in Chicago.
