Location

New York Marriott at the Brooklyn Bridge

333 Adams St. Brooklyn, NY 11201, United States

The hotel is minutes from many amazing New York attractions and is one of downtown Brooklyn’s most exciting hotels. Situated moments from the Brooklyn Bridge and just across the East River from Lower Manhattan, the hotel provides guests with an inspired vantage point to work, play and relax. Dine at one of the two restaurants, The Bar and Brooklyn Pantry, where locally-sourced cuisine and Brooklyn Winery vintages take center stage. Make a splash in the indoor pool, reboot in the fitness center which features Peloton Bikes.
