Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: I only stayed here for five days, but I will definitely never be going back. The architecture is kind of cool, but the customer service was very poor. I don't know how much these people get paid, but they must not think it is enough. Breakfast at the The Continental was alright, but it was overpriced. This hotel felt really crowded and the service was impersonal. There are many better places to stay in Chicago.

Output:
negative
