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

Example input: 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.
Example output: positive
Example explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.
Q: I stayed at the Sheraton Chicago hotel for a business meeting and had an absolutely horrible experience. When i arrived, exhausted after a series of delayed flights, I was told that my room was not ready. Not ready at 5pm, are you kidding me! After waiting in the lobby for 30 minutes I was finally called over to the desk only to be told my king room was changed to a room with two queen beds, fine, whatever. I get up to my room and unload all of my bags only to find my a/c doesn't work. I call down to the desk and the clerk tells me that they are sold out and there is no where to move me but she could discount my rooms $20. No apology. Nothing. Im exhausted and deal with my 80+ degree room. When I went to check out the next morning I find out no one even bothered to apply the discount. Again, no apology. I have never received such poor customer service in my life and will not be comming back.

A:
negative
