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: The Sofitel Chicago Water Tower in the downtown area is advertised as a four-star luxury hotel. However, modern architecture and a convenient location seem to be its only reliable perks. Room service is available 24 hours a day, but offers a limited variety of items and often lethargic service. Two bars are located on the premises, which is appealing at first. Once inside, patrons do not receive the quality of service that is to be expected and there is a complete absence of privacy, of any kind. The guest rooms are relatively spacious and clean, but a lack of adequate toiletries and personal items can interfere with a guests routine. Obtaining additional towels and grooming products is much too difficult. If you are a traveler who is in search of a relaxing and hassle-free experience, with reliable customer service, booking a room here is probably not a viable option.
