This is absolutely the worst hotel I have ever stayed at. Air Canada put us up there for a night because of a flight cancellation. Filthy smelling carpeting, the odor of the hallways was like nothing I have ever experienced. I slept on top of the bed with a sweater under my head because I didn't want to put my head on the pillow. I have noticed all other comments were relatively positive but were written by Canadians. They need to travel more, this would never be acceptable in San Francisco.
