Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Input: I stayed at the Hyatt for a two nights on a business trip. My room was oddly shaped to give a stunning view of the river and NBC Building. Both the room and the bathroom were spotless and the room had an air purifier which ran silently. The hotel was well staffed with individuals who were knowledgeable about both the hotel and the surrounding area. I would not hesitate to stay here again and plan to return with my wife for a weekend. 

Output:
positive
