Question: Thanks Sheraton Towers for the invite to enjoy your indoor pool while a guest at your hotel recently. I did not know that the skyline of Chicago could be so beautiful or an afternoon at the pool so enjoyable. I'll be back soon and look forward to a seeing Chicago again.

Answer: positive

Question: Just returned from 2 nights at the Ambassador and I have to say that I am very happy that I chose this hotel. It is true that this is an older hotel. But it is well kept and it does not lack in style and grandeur. (think of the hotel from the Shining, minus the elevator of blood and creepy twins.) From the check-in desk to the surprise turn down service from the maids, I was made to feel like royalty. A special acknowledgment goes out to the doormen who helped me with all my tourist questions. Also the location of the hotel is great. Close to all the action, but on a quite residential street with beautiful old mansions. I also got a sweet $89 per night room by booking on travelzoo. That was just an added bonus however. Even if I paid $200 per night, my impression of the Ambassador would not change. Highly, highly recommended.

Answer: positive

Question: I only stayed out with my boyfriend for one night, however enjoyed my stay. The staff was friendly, the room was nice and clean, the hallways and ballrooms etc were elegant. Room service was quick and had good options to choose from that actually tasted great. The staff was able to extend our check out time for an extra 1-2 hours without an extra charge to the room. Great location too! Walking distance from the Art Museum, Millennium Park, Grant Park (right across the street) and a quick cab ride to McCormick Place. If I were in the city again I would love to stay there again.

Answer:
positive
