Input: I stayed at the Sheraton Chicago Hotel and Towers recently, and I was completely dissatisfied. When I arrived the clerk was very rude to my guest and myself. We finally got all of our things figured out and went to our room. There is a river right outside and i constantly heard boats passing by. My bathroom was disgusting and not to mention, very small. I did not have a very pleasant experience at the Sheraton Chicago Hotel and Towers.

Output:
negative
