4301 Massachusetts Avenue NW 4001Washington, DC 20016

Tucked along the prestigious Massachusetts Avenue corridor in the heart of upper Northwest DC, welcome to unit #4001 at The Greenbriar. This beautifully renovated studio has been transformed top to bottom this month — move right in and enjoy everything new.
The brand-new kitchen features white shaker cabinetry, granite countertops, and stainless steel appliances, all set on fresh new tile flooring. Freshly refinished hardwood floors and a crisp coat of paint give the space a clean, bright feel throughout. The spa-inspired bathroom is equally polished — think full tile surround, a new vanity, and sleek matte black fixtures that feel straight out of a boutique hotel. Serene treetop views complete the picture, offering a peaceful, green backdrop that feels miles away from the city bustle.
And then there's the detail that truly sets this listing apart: a deeded garage parking space (A2-25) available for purchase for $35,000— an extraordinary rarity for a studio in this building or any building. Pair that with a condo fee that covers all utilities, and the value here is undeniable.
The Greenbriar delivers the full-service lifestyle — 24-hour concierge, a stunning rooftop terrace perfect for sundowners with a skyline view, and a pet-friendly community that welcomes your four-legged family members too.
Step outside and you're in one of DC's most coveted and quietly beautiful neighborhoods. Walk to American University, wander the trails of Rock Creek Park and Glover-Archbold, or explore the charming boutiques and beloved restaurants of Tenleytown and Spring Valley. All the energy of the city, with the serenity of a neighborhood that still feels like home.
Whether you're a first-time buyer planting roots in DC, an AU student whose parents are looking for a smarter alternative to rent, someone seeking a sophisticated pied-à-terre in the capital, or an investor adding a turnkey, income-generating asset to their portfolio — this one checks every box. Welcome to The Greenbriar.
