Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:Although the Millennium Knickerbocker Hotel Chicago claims to be an affordable upscale hotel in the heart of Chicago, it is somewhat expensive, starting at $200 per night. There are very few special discount rates available for the budget conscious traveler. The rooms are modern looking and a little less cozy than one might prefer. The carpeting in the rooms is a little outdated and somewhat dirty in a few areas. The views from the rooms are not as great as they could be. The hotel seems to be understaffed and the heating unit in the room is hard to adjust to the right temperature. Although the hotel is located on Chicago's famous Michigan Avenue, it is a $40 taxi ride from O'Hare airport and a $36 taxi ride from Midway airport, both rather pricey options. If you chose to drive there, the valet parking charge is a hefty $53. Again, not very budget friendly. All in all, even though the Millennium Knickerbocker Hotel Chicago is close to some of the major Chicago attractions, it is only an average hotel on many levels.

Solution:
negative
