Charming, but Prepare to Pay to Park!
This is a charming old hotel. The oldness of it didn't bother me at all. I was in the South Tower and the room was cavernous. The ceilings very high, the bed very comfortable (however, I was glad I had my own pillow with me). The bathroom spacious and clean. The shower was hot and had plenty of pressure. My room did have the METRA under the window, but also a view of Sears Tower.
My friends however were in North Tower and had a STUNNING view of Lake Michigan and Buckingham Fountain. I was a little jealous. 
The parking actually left me a little sleepless. I didn't go through valet, but parked my car in the garage. It was confusing, not well marked. The attendance were pushy, rushed me to get my things out of my car, overall not very pleasant. At the time I was the only car they were attending to, no need to rush me. They did not instill confidence in handing over the keys to my 6 month old car. I felt as if I had been scammed somehow. Needless to say, the car was fine after I paid the $40 ransom (I know it is Chicago, but that was ridiculous). They say "in and out privileges", but that isn't necessarily true. You still have to pay when you leave and come back, I must have a different definition of "in and out privileges." The gentleman I spoke to in the morning was much more helpful and pleasant to deal with. When I checked out of the hotel I asked if the parking attendance were actual employees of the hotel and they said no. Although the sign says, "Hotel Parking". Just be prepared to pay whether you valet or not.
I might stay there again, but try to get the North Tower with that gorgeous view my friends had. Even though it is out of my normal price range (my room was paid for by my friend).
"They" say it is haunted, I did not have any ghostly encounters. The long, "mazey" hallways reminded me of Ghostbusters, I half expected Slimer to come around a corner. :D There is a floor 13, so if you happen to be superstitious, you might want to request to NOT be on that floor when booking. 
I did not use any other amenities, so I can not comment on those.
