Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:I stayed at the Affina Chicago for my anniversary. The hotel is in a great location, but that doesn't make up for the poor customer service and rudeness of the staff. It looked like the cleaning crew forgot to vacuum from the last guest since there was hair on the carpet. I spent more money than I would normally, hoping for a luxury experience, and left very unsatisfied.

Solution:
negative
