Great location, small room
We stayed at the Marriott Chicago Downtown for a recent business trip. Location was excellent, service was good, but the room was small and very noisy. Upon check-in, we failed to notice that this room bordered the elevator shaft, which rattled away all night ever time someone used the elevator. Also, we could hear every word spoken in the room adjacent to ours (particularly those spoken at 3am!). In hindsight, I'm sure we could have asked to change rooms, so I certainly don't fault the hotel. Just beware of it if you are not a heavy sleeper. The building is aged and some areas could have used some work, but the views were unbelievable from the higher floors, so it's worth asking for something with a view if you will spend any time at all in the room. If you're looking for breakfast, the West Egg was a great little diner just four or five blocks away. Ask the concierge for a list of breakfast places within walking distance.
