Great location
This Marriotts is right in the middle of things you will want to do and see. I had planned to take buses and trains but ended up walking to all the tourist sites. The tour boats are two blocks away. The art museum, symphony hall, and the bean are less than a mile. There are tons of great restaurants nearby. The hotel was fine, a bit dated, but about what I expected. The staff is extremely friendly. So friendly, in fact, that they cheerfully sent us the wrong way to a grocery store. Our room was on the 43rd floor facing south. The view was magnificent and, while we could hear the street noise, it wasn't bothersome. I overheard many guests complain about the sirens from emergency vehicles. I recommend that you ask for a room up high and away from Michigan Avenue. My only complaint is the business (executive) lounge. It was very crowded and the food is put out mostly in one corner. It was difficult to get breakfast without getting bumped and fighting the crowd. A little more planning could make this lounge a lot more comfortable. Overall, I would stay here again.
