Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:If you have not tried the Millennium Knickerbocker for a stay in Chicago, do it now! We have stayed (and enjoyed) at the Drake, Intercontinental and others, but we always now come back to the Knickerbocker. Why? If "Charlie" the doorman is on duty and you pull up, he will welcome you. He'll probably ask your name. Why? Because he wants to call you by your name every time he will see you during your visit. Somehow he even lets the other employees know your name and all of a sudden, doorman, receptionist, bellman, waiter are referring to you by name. The employees are what makes this hotel. Yes, it has everything to offer like all hotels, but the others don't have the fine people (including the cleaning staff) these folks have. Try it, you will like it. We look forward to our next visit already...

Solution:
positive
