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

Example Input: We booked our hotel stay thru Yahoo and requested a room for 4 with 2 beds. When we got to the hotel, not only did they not have a room for us (we pre-paid!), but they said they could not guarantee what we had requested online, they could only give us what was available. The hotel staff was rude and condescending and only after I got upset did they finally tell me they did have a room for us. If you book online - beware! You may not get what you paid for. They did not stand by their promise they advertise in each room.

Example Output: negative

Example Input: OK, we are back from the Knickerbocker and I would give it the best rating. I can't believe the bad reviews. I got a priceline deal, and I still got a fine room, clean, up-to-date furnishings (OK a little traditional for my taste) and smoke free. Someone said in another thread that some people write prank reviews. I think such people should get a life because people want to read the truth. Here it is from my point of view. Both rooms on 10th floor. Regarding the size of the rooms. We had two rooms. One was a 2 double bed room. It was about 20' x 15'. Each double bed had valences that were kind of mini-canopies. The furniture, bathroom tile, shower (no tub), wall paper and paint had been done in the last few years. A Chinese inspired cabinet held TV, coffeemaker, ice bucket, and mini-bar. Three separate levels (TV, ice/coffee, and minibar) The other room was called "Queen executive". This one had queen bed with more of a canopy than valence, sofabed, two TVs and terry bathrobes. Also about the same size but different configerations. One TV faced the bed, other in the three level cabinet, the sofabed. Smoke in the lobby. There is a bar to the right of the entrance. It is an open arrangement so that I am sure the smoke comes from bar to entrance door. No smoke smell in no-smoking rooms. Cost of rooms $75 on priceline plus taxes. Very good value one block from N. Michigan Ave. Only complaint. Concierge said that the free trolley didn't go down Michigan Ave to Field Museum/Museum complex when in fact it does. Was this ignorance? or trying to throw more business to taxi? Either case, not good. He said at this time of year free trolley only goes to Navy Pier during winter....which is clearly incorrect. 

Example Output: positive

Example Input: If there is ever a Hotel you should stay at it is the Sheraton Chicago Hotel and Towers. This is the most beautiful Hotel I have ever seen. This Hotel has more than you will ever need or want. You can pick from a room that is decorated in great taste. There is a in room refreshment center,high speed Internet, 32 inch television ,coffer maker with great coffee from Starbucks. You could get a suite or the Presidential suite with more room than you will ever need. The room is over 2000 square feet.It over looks the Chicago River. There is plenty of activities with a great fitness center and a big indoor heated pool.The sauna was just wonderful. If you want to sight see in the area you can walk to the Navy pier,or Art Institute. When you come back hungry you can eat at the elegant steakhouse which had some of the best food we ever ate. Have a few drinks at the great bar, then create your own burger at the Chicago Burger Company. The staff was very friendly and super helpful. The Hotel was the cleanest I have ever seen. I will come again and again. A big thumbs up to this great Hotel.
