Rising 39 stories high in the skyline, the magnificent Marriott Marquis San Francisco Hotel exudes an essence of modern luxury and the convenience of an extraordinary downtown San Francisco hotel. Just south of Market Street, this San Francisco, California hotel next to the Moscone Convention Center is steps away from the Yerba Buena Gardens, renowned museums and cultural attractions, world-class shopping on Union Square, and AT&T Park home of the 2010 World Series Champions, the San Francisco Giants.
