The Marriott SF is a hotel you can only hope to endure if you are attending a convention at nearby Moscone center. It is a tenement of a building, with as many hotel rooms as can fit a block-like structure extending to their penthouse lookout bar (which I missed – what energy I had was used in hiking to my room). Nothing is visibly wrong with this hotel, it’s just a bit impersonal and machine-like in its attendance of corporate housing needs.
