Welcome to your new home, tucked along a charming network of alleyways in historic Washington Square West. Whether you arrive via the garage—equipped with an electric car plug-in—or through the private, gated patio with custom built-in planters and a bench, you’ll feel at home at this serene retreat in the heart of Center City. Stepping into the home, you are met by the charming living room, complete with a wood burning fireplace, built-in coat storage and bench, a massive picture window overlooking the patio and the lower level, and garage access. The living room and picture window open to the kitchen below, allowing natural light into the space. The kitchen has been tastefully renovated with classic white shaker cabinets, black granite counter tops, stainless steel appliances, and plenty of space for both dining and relaxing. A flexible nook located behind the kitchen is ideal for a home gym, study zone, or extra storage, and the half bathroom makes this level especially practical. There’s also a mechanical room and a separate storage room. Upstairs, you’ll find three spacious bedrooms, each offering generous closet space and large enough to comfortably accommodate king-size beds. The second level features a bedroom with access to a private balcony, as well as a versatile open area currently used as an office. This space is enhanced by two floor-to-ceiling windows and a wall of built-in bookshelves, making it ideal for use as a den or library. A conveniently located laundry closet adds functionality to the area, while a full hallway bathroom serves both rooms. The third floor is home to a generous primary suite, complete with floor-to-ceiling windows and ample closet space. This level also includes another full bathroom and an additional roomy bedroom. At the very top, a roof deck provides space for outdoor dining, entertaining, and enjoying the city skyline. Throughout the home, you’ll find terrific natural light, hardwood floors, recessed lighting, tasteful updates, loads of closet space, and central air. Garage parking and a quiet setting on peaceful side streets make daily life feel a little easier. All this, just a short walk to neighborhood staples like Whole Foods and Acme, and within minutes of Jefferson, McCall school catchment, and everything Center City has to offer.
