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

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.
Solution: positive
Why? Review writer likes the hotel. There are strong positive words like 'impeccable' and 'great'. Therefore it is classified as a positive review.

New input: My wife and I were very much looking forward to our stay at the Hotel Allegro in Chicago. We had been looking forward to a romantic getaway. I have to say Hotel Allegro was a disappointment for both of us. This is a pet friendly hotel - we knew that going in. But we were shocked by the fact that we found pet hair around the room we were given. In the carpet and even an amount on the bed cover. Very shocking for the price we were paying. When we called the front desk it took over an hour for someone from housekeeping to stop by. Past this - the room itself - it has flair I guess, but I can't imagine it is the right flair for many. The colorings used a bright blue on the bed and a muted yellow, designy wallpaper. Neither myself or my wife found it relaxing at all. I can't imagine many would. It really was off-putting. Overall, the experience was a check minus in my book. Will not be looking to return any time soon.

Solution:
negative
