Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:I stayed at the Sheraton Chicago Hotel and Towers in December of last year and had one of my worst hotel experiences ever. First, when I went to check in, I was completely ignored by the staff, they were rude and seemed to have better things to do than help me check in. When I got to my room, all the way on the 23rd floor, the room was dirty and had not been cleaned. So back down to the lobby and they seemed to feel it was no big deal and gave me another room. I went back to check and the new room was dirty also. There were pubic hairs on the bed and in the bathroom. It appeared the maid only went into the room and picked up trash and made the bed but did not clean. All I can say is YUCK! My next visit to the lobby the staff gave me an attitude about having to transfer me to another room AGAIN! Extremely poor customer service and gross rooms. I felt like I was staying at a $30 a night roach motel, not the $250 a night Sheraton. My advise is to stay away.

Solution:
negative
