Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

Example Input: The Hard Rock is glossy and sexy, but an absolutely fantastic hotel.... I was in town for business and stayed here because of it's location, but I absolutely understand why tourists would like it...right on the river, cool art deco building and Millenium Park is just down the street. Regardless- the room was clean, the staff was friendly, but NOT annoying and the bar was fun. I was comfortable having a couple of drinks alone at the end of the day - they were GOOD! I'll definitely try it again!

Example Output: positive

Example Input: Didn't get the room we were promised. Kind of room we had reserved (2 queens) "wasn't available. they then squeezed 3 adult ladies into 2 singles and a blow-up bed. Had to pile furniture on top of tables to get it in! Very unsatisfactory!! Will not return, will not recommend. Will tell people going to Chicago to NOT stay in your hotel. When I next visit Paris nextspring, I intend to stop at your world headquarters to tell them what I think of the Chicago facility.

Example Output: negative

Example 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.

Example Output:
negative
