The room was clean on arrival and the beds were comfy. You can't adjust the temperature of the A/C in the room; it's either on or off.
Unfortunately, we had some issues with the water in the bathroom. One day after being out all day, we came back to find the floor of the bathroom was soaked. The engineer came up quickly but he wasn't able to replicate and therefore fix the problem. Housekeeping came up shortly after to dry the floors and replace our towels. The next night--the last of our stay--when we went to use the shower, brown water was coming out. We had to get an engineer out again to fix it. Housekeeping never did come up to clean up. Also, a battery in a smoke detector in the hall went out and started chirping. I mentioned it when I called down about the brown water and I mentioned it to the engineer. It was still chirping when we checked out the next morning.
Overall, our stay was okay. The location was amazing; we could see the fountain in Millennium Park from our window. I think the water issues might have just been because the building is so old/historic.
