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

Input: Consider Input: We reserved a room with a sleeper couch a few weeks before our stay. After checking in and unpacking, we discovered that the sleeper sofa had been removed (supposedly during renovation). The front desk clerk and bellman never mentioned that there was no sleeper sofa even though they saw all 4 of us check into the room. Colleen, one of the managers, was argumentative and did nothing to resolve the problem. We ended up having one of our children sleep on the couch and the other slept on an antiquated rollaway bed. We never spoke to the general manager who was conveniently "absent from the hotel" during most of our stay. We stayed here on more than one occasion over the past decade and had never encountered such incompetence. We had to make several phone calls to receive a miserly discount and we never received an apology. The lack of training of the staff was clearly evident, as was the cavalier attitude of the management.

Output: negative

Input: Consider Input: For Top Class Treatment Choose Hotel Allegro. In all of my years of buisness travel and vacationing, I have never been more happy with the service at a hotel than I was at Hotel Allegro. I searched many hotel websites looking for the perfect hotel to spend our honeymoon, and Hotel Allegro seemed like the right choice. Soon as I walked into to their elaborate lobby area, it was like I was a big shot on Wallstreet, the service was excellent and the best part, they allow animals. They treated my little dog Johnny like he was royalty. They have everything you could ever need in a hotel, from in room spa service to a workout center. They even made sure that I had all of my drinks and amentites ready for the Monday night Bears game. If I were to give have to rate it from a 1 - 10. Id have to give it a 10 many times over. I highly recommend Hotel Allegro in Chicago Illinois and I will be back again.

Output: positive

Input: Consider Input: WARNING! My stay at the Talbott Hotel will go down in history as one of my worst experiences staying in hotels. I was excited for a weekend getaway with a few friends. After receiving a few positive recommendations and looking at their website we decided to stay at the Talbott. They were promoting up to $30 breakfast credit per day. And breakfast is my favorite meal so this was already looking like a great time. Upon our arrival we were greeted by an employee (which we wouldn't have known had he not told us) that was not only rude but made sexual advances at one of the ladies on our group. Once we talked with a manager about the incident outside he assured us that he would take care of the issue and even upgraded us to King suites instead of the double size rooms we originally reserved. If someone had blindfolded me and took me into one of these rooms I would have sworn we were at Motel 6, not a luxury hotel in Chicago. The linens were stained, room smelled of smoke and had another odor that was similar to old cat pee. I was truly disgusted. After a night out on the town we came back to our disgusting rooms to get some sleep. The next morning I was excited for our breakfast that was highly recommended by the hotel and other guests. I have to say it was one of the worst breakfasts I have ever eaten. The toast was stale, eggs were made from powder instead of real eggs, and the juice they served was sour. I would never recommend this as a place to stay. I would suggest the Red Roof Inn over this place anytime.
