Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:My son & I joined my husband on a work trip. We planned to swim while he was working. We overheard a lady asking when the pool would open as as we were checking in. Though my son was eager to swim as soon as we checked in the pool was still closed at 630 pm. We gave up & went out for the evening. We had a very noisy sleepless night. We weren't facing MI ave, but still heard sirens and I'm not sure what the other noise was, but it sounded like a malfunctioning hand dryer in our ceiling that would sound off about 20x an hour throughout the entire night. I called the front desk the next morning and was told the pool was open, so my (very excited) son got his bathing suit on and we got to the fitness center only to be told by housekeeping that the pool was closed for construction. Upon calling the front desk again the lady claimed she was unaware of the maintenance crew's actions & on my insistence she said she'd look into it. A gentleman called back an hour later & said the pool should open at 5pm...it was 9am. It is now 6pm & we still haven't even seen the pool. We check out tomorrow. We passed up time with grandparents who are in for the holiday to "swim in Chicago." Needless to say we are VERY disappointed.

Solution:
negative
