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: Spent three nights in Chicago at this property. First of all, I have to say that it would be hard to imagine a better location as it is perfectly situated on the Magnificent Mile close to terrific restaurants, the Art Institute and Orchestra Hall. The hotel has two sides - the historic tower and a new wing. The rooms are larger on the historic side but generally are looking a little tired. This property needs to be renovated. Some observations: The junior suite I had was laid out strangely. A small bedroom and smaller sitting room separated by a corridor off of which was the very large bathroom. The mirror over the sink was not over the sink but skewed to the right - made shaving a challenge and messy. While descending in the elevator one morning, it started shaking so violently that I could barely stand up. It stopped on the 11th floor and I was greeted by an extremely worried looking hotel employee who had a technician shut it down. (This experience was far more powerful than coffee in helping me wake up - an adrenaline rush certainly cures sleepiness!) Reports from my group were of sinks stopped up, exposed bolts in rooms, and generally things not working. Now the good news - the staff is terrific. They make you feel welcome, are personable, have their own personalities, great service in the bar and really went the extra distance to help. I wish they had a better property to work in.
