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: The elevator system was impossible. It seems they were trying to improve it but only made it worse. Many people waited 15+ minutes and some bailed out to the stair wells. It happened several times. I had read about it before booking but guess I didn't take it seriously. It'd be a deal breaker for any future return unless I heard clearly it was improved. Also, I always think it's lame that you have to pay extra for WiFi. Area recommendations North Michigan Avenue and Lake front areas are best.

Output:
negative
