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

New input case for you: After a my stay at the Millennium Knickerbocker Hotel Chicago I contemplated the the poor quality of my experienc there and felt the need to document it. While the amenities were plush, the service of the staff was lacking. Upon check in, my reservation was "lost" and it took over 30 minutes for the manager to make arraingments for my stay. There was no offer to upgrade me or comp me in any way. Room service did a poor job in cleaning my room and left wet towles in the bath room. A used coffee filter was left in the coffee pot for me to clean out. I am not sure my sheets were changed out. When I checked out, the bell hop dropped my laptop and destroyed my hard drive leaving me to scramble to recover the report I spent days creating. Overall my negative experience has left me wondering if they train thier staff on the proper way to attend to their customers. I will be relunctant to stay with them again until I am assured they have focused on trainging their staff better.

Output:
negative
