Stayed for two nights. The frontdoor of the hotel is small so can be hard to find.
The room is suite-style and it has a kitchen with multiple cookwares, although there are many resturants around and I doubt anyone will really cook during the stay. The room is not super spacious but larger enough for being comfortable. The wall is relatively soundproof, that the noise is mostly from outside rather than your neighbors. Due to the narrow street of Chicago you won't have much view from your window, but some rooms, including mine, can see the Willis Tower.
The location of the hotel is great, as it's in the center of the downtown. I used to think Chicago is dangerous, but at least around the hotel, I did feel pretty safe even at the night.
Free breakfast is offered, and despite being the continental breakfast that you can see anywhere else, the quality is good and there are some variation from day to day.
Didn't use other facilities so cannot comment.
