Teacher:Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Teacher: Now, understand the problem? Solve this instance: If I didn't have to stay here, I wouldn't. Without exception, I swear I am not lying, every day of my stay brings a new problem. Over the past 3 months, I have stayed here 6 times for 3 nights at a time; problems every time. From the wrong food with room service, to room keys that dont work, unrefreshed bath towels, forgotten and dirty in-room coffee service, unclean ice bucket overnight, forgotten room cleaning, inability to connect to the Internet....I'm too tired to keep writing all the problems. For the price of this chi-chi downtown hotel, I expect more. Finally, their team is certainly not trained in customer service. The front desk teams have attitudes, and Aria's hostesses think they are something else. I'm stuck using this hotel since it is adjoined to Aon, but I would never go back if I had a choice. The only good thing is the food at Aria - outstanding.
