We stayed in the Waldorf Astoria for one night in September this year on our visit to Chicago. we pulled up at the hotel and the polite valet welcomed us and took our car and we was checked into the hotel promptly by the desk staff. We was shown to our room and the bellboy offered to take our bags.
The twin room was huge by city standards and felt very fresh and modern. The room was equipped with a huge tv, speaker with ipod dock and even a tv in the bathroom mirror! Unfortunately i didn't have time for a bath so didn't make use of the novelty.
We arrived in the afternoon and went out for dinner in the city so didn't make use of the Hotel's restaurant. I did use the hotel minibar which had a great collection but wasn't priced as bad as you'd expect from a hotel of this quality. The beds were really comfy and i had one of the most amazing nights sleep i've ever had. While we was out the maid serviced our room in the evening.
We checked out late morning stress free, apart from the valet bill which was over $50 for one night! I did try to tip the valet driver but he turned it down (probably felt sorry for me for forking out so much!).
Summarised this is a great hotel in a great location in the heart of Chicago and is definitely recommended. It's quite pricey as you'd expect, but compared to other 5* Hotels it wasn't priced badly at all really. Would definitely return
