Part 2. 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
Answer: true
Explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is true as the polarity mentioned.
Part 3. Exercise
Review: This is a great hotel! From the doorman who greeted us as we arrived, to the young man at the reservation desk to the young woman serving complimentarily wine, everyone was very friendly and helpful. We were "strangers but for a minute!" The room was extremely clean, well appointed and we had a pretty view of the Chicago River, especially enjoyed from the large window seats. Loved the purple polka-dot paper on the toilet paper roll! Hallways were large and quiet. The restaurant next door, South Water Kitchen is very nice too. The location is in walking distance of the theatres, parks, the river (take a cruise), Michigan Ave. It's ideal. The only negative is that the concierges were not nearly as friendly or inviting as the rest of the staff nor were they very helpful. For a self-sufficient traveler, you wouldn't really need their services (although it is nice) but for someone coming to Chicago for the first time, a concierge can be very helpful. I would definately stay at this hotel again and would recommend it.
