Last month the penthouse apartment at 250 West Street, which is found in the middle of TriBeCa's landmark historic district, went on the market for $39.5M. With views of the Hudson River (nearly 120 feet of frontage, to be exact), this residence has its own private entrance on Hubert Street — complete with your own personal loading berth and lobby, where you’re an elevator exclusive to the penthouse takes you right up to the 7,250-square-foot home.
