Detailed Instructions: Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Problem:Under the gloss of a nice building, friendly staff, and a wild set of items in the minibar, this is somewhat below-average hotel. In particular, the bed and chairs were some of the least comfortable I ever encountered. After two nights, my wife and I were practically cripped by bed pain. We complained to the staff and were immediately offered the chance to switch to a different room, but the other room was furnished identically. The owners of the Omni need to stop spending money on bath salts for the rooms and invest in the basic comforts. I should not be lying on the floor, trying to unkink my back, thinking longingly of the last Red Roof Inn I visited.

Solution:
negative
