Teacher: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Teacher: Now, understand the problem? If you are still confused, see the following 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: positive
Reason: 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 instance: Upon entering my hotel room at The Palmer House Hilton I immediately turned my nose up at a foul odor coming from the bathroom. After placing my bags on a poorly made bed I walked into the bathroom to find the last visitor had failed to flush the toilet. I immediately called room service and asked for a new room. They apologetically told me there were no other rooms available but would send someone right up to handle the mess. After oh around a half hour of waiting a very angry maid knocked at my door. She seemed very irritated to have to deal with the mess and looked at me as if I should have been the one dealing with it. After the room was cleaned up she turned to me as if asking for a tip. I hesitated and she angrily stormed out of the room. I thought things would run smoother and tried to relax with an ipod. Yes you can use your ipod in the room however what they fail to mention is the constant white noise because the signals are so poor. And nothing could compare to the remote control heating and air. When I was able to get the buttons on the remote to work the temperature seemed to change on its own. If I wanted hot air it would slowly get colder and vise versa. After giving up on a nice television program I decided to retire to bed. Egyptian sheets? Right! All I can say is I found myself early to check out and in a new hotel within the next hour. If you value your back do not rent a room from this hotel.
