Built in 1900 by Paul J. Pelz, 2201 Massachusetts Avenue is one of Embassy Row’s historic mansions. The building, known as both the Miller House and the Argyle Guest House, is a contributing property to both the Sheridan-Kalorama and Massachusetts Avenue Historic Districts. Now a 4-story, 9-unit, boutique condominium, the units in 2201 are rarely available. The building can be noted for a rooftop terrace and a unique wood carved staircase in the lobby. Its location on Embassy Row is convenient to both Adams Morgan and Dupont Circle.
