Definition: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: We chose to stay at the Hilton Chicago because it was in such a centralized location- everything that our family wanted to do in town was located so close! What I didn't expect was for the beds to be so comfortable. I can't remember when I got a better night's sleep. The staff was very friendly and the hotel grounds were impeccably kept. We'll be returning to the Hilton Chicago the next time we're in town!

Output:
positive
