Welcome to 400 Massachusetts Ave NW, where space, comfort, and location come together in the heart of Mount Vernon Triangle.
This 1-bedroom, 1-bath condo offers exceptional value in one of DC’s most vibrant and walkable neighborhoods. With SOARING 9-FOOT CEILINGS, HARDWOOD FLOORS, and a sun-filled southern exposure, the home feels bright, airy, and significantly larger than most one-bedrooms in the area.

The spacious bedroom suite features a large en-suite bathroom and three additional closets—a walk-in closet, storage closet, and linen closet. Within the bedroom, a built-in workstation with integrated cabinetry and shelving provides an ideal work-from-home space.
The owned, assigned underground parking space conveys with the sale—a valuable asset offering flexibility for personal use or potential rental income. Spaces in the building are in demand and are often rented by residents (commonly $200–$300/month). The parking space also includes a dedicated bike rack for added convenience. Move-in ready with recent updates, including fresh paint, a new electric range with ceramic cooktop, updated lighting, and modernized bathroom hardware, including vanity lighting, sink and bath faucets, and a shower head.
Amenities: This full-service building features a 24-hour concierge, rooftop pool with sweeping city views of iconic monuments, grilling stations, a sun deck, outdoor lounge and dining areas, a seasonal herb garden, a state-of-the-art fitness center, a club room, and a business center.
Ideally located in a walker’s paradise, with easy access to restaurants, shops, and cultural destinations such as the National Building Museum and National Portrait Gallery. Exceptional transportation options include multiple Metro stations (Judiciary Square, Gallery Place, and Mt. Vernon Square), Union Station just minutes away, bus lines, and quick access to I-395. Also just blocks from Capital One Arena and CityCenterDC, one of DC’s most sought-after shopping and dining destinations....
