Given the task definition, example input & output, solve the new input case.
Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Example: I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.
Output: positive
Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

New input case for you: OK, we are back from the Knickerbocker and I would give it the best rating. I can't believe the bad reviews. I got a priceline deal, and I still got a fine room, clean, up-to-date furnishings (OK a little traditional for my taste) and smoke free. Someone said in another thread that some people write prank reviews. I think such people should get a life because people want to read the truth. Here it is from my point of view. Both rooms on 10th floor. Regarding the size of the rooms. We had two rooms. One was a 2 double bed room. It was about 20' x 15'. Each double bed had valences that were kind of mini-canopies. The furniture, bathroom tile, shower (no tub), wall paper and paint had been done in the last few years. A Chinese inspired cabinet held TV, coffeemaker, ice bucket, and mini-bar. Three separate levels (TV, ice/coffee, and minibar) The other room was called "Queen executive". This one had queen bed with more of a canopy than valence, sofabed, two TVs and terry bathrobes. Also about the same size but different configerations. One TV faced the bed, other in the three level cabinet, the sofabed. Smoke in the lobby. There is a bar to the right of the entrance. It is an open arrangement so that I am sure the smoke comes from bar to entrance door. No smoke smell in no-smoking rooms. Cost of rooms $75 on priceline plus taxes. Very good value one block from N. Michigan Ave. Only complaint. Concierge said that the free trolley didn't go down Michigan Ave to Field Museum/Museum complex when in fact it does. Was this ignorance? or trying to throw more business to taxi? Either case, not good. He said at this time of year free trolley only goes to Navy Pier during winter....which is clearly incorrect.

Output:
positive
