I stayed here with my family when we visited Chicago one time. At the time, they were doing their renovation. It probably would have been better if we had not been there at the time, but it was ok.
The renovation was obviously needed as the hotel was quite post-war 60's when we were there. Our room overlooked an empty outdoor swimming pool that looked like it was in serious disrepair. (I think it was being renovated.) The rooms were ok, but not fancy. Obviously, the key attraction here is low Best Western prices, and close proximity to Grant Park, The Miracle Mile, and Downtown.
However, there were some upsides. The staff was extremely friendly and helpful, which is not the case sometimes at aging hotels. There was even a bellhop. In some ways, this hotel seemed stuck in time. The dining room was lovely, very '60's, but beautiful and fancy. The food was tasty, well-priced, and served by a professional and gracious staff.
Now that their renovation is done, this hotel is probably one of the cheapest and nicest hotels along Michigan Avenue, a good budget choice without staying at a motel.
