“1” Hotel is a new concept boutique hotel development in the West End submarket. Perseus Realty partnered with Starwood Capital Group to purchase and assemble 2201 M Street and its adjacent property in November 2006. Perseus Realty and Starwood are developing a 180 room and suite “1” Hotel. "1" Hotel Washington will be part of the first luxury, eco-friendly global hotel brand to combine environmentally sustainable architecture and interior design with the service and comfort of a five star hotel; as such, it will be among the first U.S. Green Building Council LEED-certified hotels in the world.
