Definition: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: We were greeted by staff with excellent customer service skills. Our room was such a pleasant surprise, from the flat screen TV, the full size shower with rain showerhead & hand held shower wand, the wall attached toilet with flushing options (on the wall), the comfortable bed, the lovely lighting options, etc.. The size of the room was snug, and very comfortable, as would be, in a historic hotel. It was also quiet, and I know that the hotel was sold out. My sister was in the room next door. We did not hear her TV. We also loved walking less than a block, to the shopping and restaurants on North Michigan Avenue. 

Output:
positive
