THE BEST 1 BEDROOM IN DUPONT! Welcome to Residence 42 at 1709 21st Street NW, a refined one-bedroom, one-bath condo offering nearly 700 square feet of sophisticated living in the heart of Dupont Circle. Located on the top floor of a boutique, newly redeveloped building by StonePark Development, this residence combines tailored design with the effortless charm of one of DC’s most vibrant and architecturally rich neighborhoods. The interior unfolds with striking chevron-patterned white oak floors, oversized windows, and an open-concept layout that maximizes light and flow. The chef’s kitchen makes a bold statement with a quartz waterfall island, designer lighting, and custom cabinetry. Integrated appliances and a full-height backsplash create a seamless, modern aesthetic, while the adjoining living and dining areas offer ample space for entertaining. The bedroom is a bright retreat, surrounded by windows and featuring direct access to a private balcony. A spa-inspired bath is wrapped in honed marble tile and features brushed brass fixtures, a floating vanity, and a glass-enclosed walk-in shower. Every finish was selected with intention and a focus on clean, timeless style. Tucked just around the corner from the Spanish Steps and only two blocks to Connecticut Avenue, this home places you in the center of historic Dupont Circle and the adjacent Kalorama neighborhood. Enjoy a stroll to Sunday’s farmers market, grab your morning coffee at Tatte, or explore local favorites like Kramerbooks, The Phillips Collection, Sushi Taro, and Tabard Inn—all within a few blocks. The Dupont Metro is moments away, making this the perfect blend of elegance and convenience in one of the city’s most beloved enclaves.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
