You will be given a definition of a task first, then some input of the task.
Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

Visiting during a busy 2day conference in Chicago. Most hotels booked solid. The full hotel allows you to meet a wide array of customers. Everyone is complaining about service, cleanliness, and overall experience. Location is good. Hotel is tired. Employees surly. Too many cool properties to choose from in this town, will never stay here again and will re-think Hilton in general

Output:
negative
