Renovations Make a Difference
Over the years I have stayed at the Hilton Chicago at least a dozen times. This large hotel was getting a bit tired. I started staying at other locations closer to North Michigan and the river. But I found the room rate at the Hilton very reasonable during a recent trip, so I went back. 
Well, it's been improved in many ways. The common areas are much nicer, the rooms have been greatly upgraded, not just new carpet or linens, this is a real improvement. Modern, but not cold or sterile. Large flat screen TVs, strong shower heads, interesting lighting. The service was superb, the free breakfast on the executive level was plentiful and good, and the beds were very comfortable. What hasn't changed is the great location, across from Grant Park, the Lake, museums. There's also one of the best authentic blues clubs in Chicago behind the hotel - it's Buddy Guy's Legends Club at 700 W. Wabash. Great new venue just down the street from the previous smaller location. If you haven't stayed here recently, I suggest you give it a try - great for business purposes, or for tourists.
