Welcome to one of Naval Square's most sought-after addresses - the coveted "Nelson" model, a stunning four-story, 2,200 square foot townhouse that checks every box and then some. Assumable debt at 2.75% (30-year) + seller's note available - an exceptional opportunity to make your numbers work beautifully at closing. From the moment you arrive, this home just feels right. Garage parking? Check. Gleaming hardwood floors, soaring ceilings, and traditional moldings that give the space real character? Absolutely. Two-zone heating and air, an updated eat-in kitchen, refreshed bathrooms, and multiple private decks to sip your morning coffee or fire up the grill? All yours. Step inside through the over-sized garage - which comes with generous extra storage - or through the front door into a sunny, welcoming den and office, the perfect perch for working from home or unwinding with your favorite show. Head up a level and you'll find yourself in a beautifully open living and dining space that flows right into a chef's kitchen designed for people who actually love to cook. We're talking stainless professional appliances, granite counter-tops, a stylish tile backsplash, solid wood cabinetry, and a kitchen island made for entertaining. A convenient powder room and a spacious deck round out this floor. The next level is where the home really shines. A well-appointed guest bedroom with custom built-in closets, a gorgeous ceramic tile hall bath, and a primary suite that feels more like a private retreat - complete with multiple professionally designed closets and a spa-worthy bathroom featuring a deep soaking tub and double sinks. You might not want to leave. Save the best for last: the top floor is a true showstopper. Vaulted ceilings, a wide-open flexible living space - bedroom, media room, office, playroom, you decide - a full-sized laundry room, and glass doors that open onto a beautifully maintained deck with sweeping Center City views. Sunsets up here are simply something else. Naval Square delivers: A 24/7 manned front gate means security is never a worry. A concierge receives packages seven days a week, and an Amazon Hub Locker+ is right around the corner. The lush grounds, resort-style pool, fully equipped fitness center, and abundant guest parking make this feel more like a lifestyle than just a place to live. Pet owners, you're welcome here too. Step outside the rear entrance and you're immediately on the Schuylkill River Trail - perfect for morning runs, evening bike rides, or just a peaceful stroll along the water. And with a 98 walk score, I-76 minutes away, and the airport just 10 minutes down the road, getting anywhere you want to go has never been easier. Perfectly positioned for professionals and academics working at Penn Medicine, CHOP, Jefferson Hospital, the University of Pennsylvania, Drexel University, or Temple University, with easy access to 30th Street Station, University City Station, and the Market-Frankford Line - and just minutes from the shops, restaurants, and energy of Rittenhouse Square, Graduate Hospital, and South Philadelphia. This is Center City living at its finest - sophisticated, convenient, and genuinely fun to come home to.
