Teacher: Given a hotel review and the corresponding polarity of review (i.e., Negative or Positive) identify if the polarity is correct. Write 'true' if it's correct, 'false' otherwise.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Review: 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.
Polarity: Positive
Solution: true
Reason: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is true as the polarity mentioned.

Now, solve this instance: Review: We reserved a room with a sleeper couch a few weeks before our stay. After checking in and unpacking, we discovered that the sleeper sofa had been removed (supposedly during renovation). The front desk clerk and bellman never mentioned that there was no sleeper sofa even though they saw all 4 of us check into the room. Colleen, one of the managers, was argumentative and did nothing to resolve the problem. We ended up having one of our children sleep on the couch and the other slept on an antiquated rollaway bed. We never spoke to the general manager who was conveniently "absent from the hotel" during most of our stay. We stayed here on more than one occasion over the past decade and had never encountered such incompetence. We had to make several phone calls to receive a miserly discount and we never received an apology. The lack of training of the staff was clearly evident, as was the cavalier attitude of the management.
Polarity: Negative
Student:
true
