Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
One 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.
Solution is here: positive
Explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

Now, solve this: After reading good reviews about the Affinia Hotel in Chicago, my husband and I decided to spend two nights there to celebrate our 30th anniversary. Unfortunately, the hotel missed the mark for us. I did not expect to find bedbugs underneath the mattress in a 4-star hotel. Because my husband and I have had a bad experience with bedbugs, as a rule, we always check underneath the mattress before settling down for the night in any hotel. When I brought this to the attention of the front desk staff, they practically accused us of planting the bugs there. I was very humiliated and disappointed in the way the situation was handled. Needless to say, we made the decision to pack our bags and went elsewhere to celebrate our anniversary. I have written a letter to the hotel chain and hope that they will be more responsive to the situation. I have also reported the incident to my credit card company to alert them that I will be refuting the charge for the one night the Affinia charged to my account because we missed the cancellation deadline.

Solution:
negative
