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

Input: Consider Input: I thought the Swissotel was a great hotel. The rooms were very spacious and clean, especially for downtown Chicago standards. Most importantly, the rooms were quiet. I never heard people in the hallways when I was trying to sleep. The only downside was that the beds were not anything special. Sure, like all hotels in Chicago, this hotel caters to wealthy and/or business clients with ridiculous minibar and parking price. However, if you are aware of that prior to arrival, its not a big deal (ie finding a different place to park the car, bringing our own snacks for the room). It would be nice though if hotels such as the Swissotel had a microfridge in the room for guest use. Staff was very helpful. Bellmen instantly got cabs upon request, and the front desk was efficient and helpful. Overall, if I can get a good rate again, I'll stay at the Swissotel the next time I am in Chicago.

Output: positive

Input: Consider Input: I want everyone to know about the awful experience I had at the Sheraton Chicago Hotel and Towers. When we arrived at the hotel, the clerk who was checking us in said that our reservation was not in the system (I had called earlier in the day and confirmed it). After speaking to the on-duty manager we were informed that our reservation had been canceled earlier in the day and that the hotel was now completely booked. We later found out that there was a convention at the hotel and that the price for the rooms had risen dramatically. I believe they canceled our reservation just so they could make more money. I for one won't be going back to this hotel!

Output: negative

Input: Consider Input: My wife and I stayed at the Ambassador East Hotel for the first 3 days of our honeymoon in mid-October. We decided to split our honeymoon up and stay in two different hotels so that we could experience different aspects and areas of Chicago in a week. I'll start out by saying that this was a great experience. At check-in, I indicated that we were on our honeymoon and were upgraded to a suite. The Ambassador East is probably a 10 to 15 minute walk from the North end of the Magnificent Mile. It is also just a 2 or 3 minute walk to a lot of great restaurants and bars on Rush. Our room itself was incredibly spacious and well appointed. Our suite (on the 3rd floor) had two very large closets, a large "living room" and a large bedroom. The bed was incredibly comfortable and the bathroom was nice enough. If I would have payed full price for this suite, I probably would have given it a rating of 4, but because the staff was so kind and because my wife and I had such a great time here, I decided to give it a five. It is also worth mentioning that the concierge was very helpful. My wife and I decided to eat at The Pump Room restaurant, but we were not very impressed. We found the food and service mediocre. The atmosphere was probably pretty neat when Sinatra used to eat there back in the day, but not anymore. Although we were unimpressed by the Pump Room, the staff were kind enough to seat us in the "Sinatra Booth" which was back in a corner and enclosed by curtains. That neat experience was really the only redeeming value of our meal here. The Ambassador East is an older hotel, but it is in a charming older neighborhood. The staff's kindness and overall charm of the hotel itself really impressed my wife and me. When we are in Chicago again, we will definitely consider staying at the Ambassador East again.
