Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

Example input: I stayed at the Hilton Chicago for my cousins wedding. The service was impeccable. Not only was the staff attentive, they were respectful and careful not to interrupt the guests or make themselves known when serving dinner. I had the chicken wellington and it was to die for! The chicken was perfect and moist but the pastry crust was flaky and crispy. They even had Pakistani dinner options for some of the guests. The amenities were great, and after an open bar the night before, the Mimosas and brunch buffet couldn't have been better! I would love to have my wedding there.
Example output: positive
Example explanation: Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.
Q: I was really expecting a lot more from a quality chain like the Sheraton, but a recent stay at their downtown location in Chicago was somewhat of a disappointment. It started with check in; I had specifically requested a room with a single king-size bed, but was told at the front desk in no uncertain terms (OK, rather rudely!) that because of some banker's convention that was going on, I should be happy with the double-bed room that was left. It was all I could do to get a lousy drink voucher for my inconvenience! The room itself was OK, nothing special though. The cleaning staff must've just been through, because there was a faint aroma of old washrags still in the air. The internet jack wasn't working. It took more than two hours for a maintenance guy to come up to fix it, no apologies given. For the price, I really expected more in the way of customer service from Sheraton. I guess they're really no better than anyone else these days!

A:
negative
