Overview

Step outside and you're three blocks from three Metro lines, minutes from Capital One Arena, the National Building Museum, and some of the city's best dining and nightlife. I-395 is right there for a quick trip to Virginia or a longer road trip adventure. This is one of DC's most connected addresses — and 400 Mass Ave puts you at the center of it. Unit 414 is a one-bedroom plus den spanning 950 square feet, with an open layout that gives you room to live and room to host. The kitchen is built for it: generous counter space, ample cabinetry, and a configuration that opens directly to the living area so you're an excellent host and cook in equal measure. Hardwood floors run throughout, soft morning light fills the space, and storage is abundant. The den works however you need it to — home office, guest room, creative space — and in-unit laundry and an assigned garage parking space mean the practical side of city living is handled. The primary bedroom fits a king with room to spare, with a connecting bath that boasts a walk-in closet with built-in shelving. A linen closet and generous under-counter storage complete the space — perfect for getting ready for work or a night out, with a shower/tub combination rounding it out. Above it all, the building matches the unit's ambition: rooftop pool and sundeck with sweeping views of the Washington Monument and Capitol dome, BBQ grills, a party room, fitness center, business center, billiards room, and 24-hour concierge. An all-season entertainer's dream — whether it's an everyday gathering or a front-row seat to the Fourth of July. Everything you need, exactly where you want to be.
