Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: I booked my room at the Sheraton Chicago Hotel and Towers somewhat reluctantly; I was not enthusiastic about spending over $200 on this room after seeing the lackluster photos on their website. I was pleasantly surprised when I arrived that the lobby did not look as stuffy as it did online. Unfortunately, my hopes were dashed once again when I arrived at my room. I say 'at' because after discovering my newly issued key was not working, I had to wait ten minutes before someone finally came to let me in. The room was painfully small-- if I didn't know better I would have thought I was staying at a Red Roof Inn! The "sweet sleeper bed" had stiff and scratchy sheets, with a cheap-motel-thin coverlet. The disappointment continued after I entered the bathroom and found that it not only reeked of smoke, but also outfitted with the cheapest trimmings possible. I stayed my two nights, and was surprised to find out that all sorts of other charges were added to my room (for which I was not responsible), charged on demand movies, an empty mini bar, AND for smoking in the bathroom. HAH! I have stopped payment on my credit card, and most certainly will not be submitting myself to this horrific experience again.

Output:
negative
