Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

Input: Consider Input: Often visit Chicago, but this was my first stay at this location. Was able to secure a good rate through travelzoo. Thought the room was clean and was nicely decorated. Was very disappointed in the service. Stayed on a Saturday night - waited 20 minutes for extra pillows - called for 15 minutes but found out the third shift crew came in 20 minutes late. Also received an incorrect folio under my door(another guests that was staying at this location). I called the front dest to inform them of the error - and they explained that this was made in error and would be corrected. I opened my credit card statement and found that I was charged for three different rooms - one on the date of my visit and two a week later. I called the hotel and guest services took the information and forwarded to their accounting department. Received a message to call the billing department, have called three times - but have not received another reply back.

Output: negative

Input: Consider Input: Just returned from a 3 night stay at the Talbott. This was our first visit there, and I can honestly say that I wouldn't stay at any other hotel in Chicago. From when we first were greated by the bell captain until our final departure, the staff was nothing less than amazing, always greeting with a smile and can I help you attitute. The room we had (1508) was very spacious and comfortable. The bed was probably the most comfortable that my wife and I have ever slept in (including the Four Seasons). Had great breakfasts and drinks at Basil's. You would be missing a fantastic experience, if you didn't stay at the Talbott.

Output: positive

Input: Consider Input: Nestled just off the beaten path and about two blocks from the river the Fairmont Chicago offers an excellent location to operate as home base for your trip to Chicago. The staff were friendly and helpful, arranging many of the sightseeing events we enjoyed while in the city. There are many attractions withiin easy walking distance (The Art Institute is a must see and Millenium Park is a fun visit). The architectural tour by river departs a dock that is very close to the Fairmont and there are lots of restaurants nearby. The rooms were excellent and the club room is worth the extra expense. We would definitely stay here again.
