You will be given a definition of a task first, then some input of the task.
Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.

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
