District Living

Live dynamically at Lydian, brilliant studio, one, and two bedroom apartments at 400 K. Inspired by the Lydian musical scale in jazz composition, the building is a stunning addition to the dynamic Mount Vernon Triangle neighborhood, just steps from a quick morning latte at A Baked Joint or leisurely dining al fresco at Alta Strada, and within easy reach of three Metro lines, New York Avenue, and I-395.
