About This Home
What if home came with a rooftop overlooking downtown, a private lounge, fitness center, heated parking, restaurants just an elevator ride away, and weekends free from mowing, shoveling, or exterior maintenance? Welcome to Washington Square, where you're not simply buying a condo, you're gaining a full membership to downtown Sioux Falls. Located on the 5th floor, this bright, south-facing residence is filled with natural light while offering a surprising sense of privacy above the city. The open-concept kitchen, dining, and living areas create an inviting space for everyday living and entertaining, while the private covered balcony is the perfect place to enjoy your morning coffee or unwind at the end of the day. Better yet, the HOA covers water, hot water, trash service, and geothermal heating and cooling, making ownership as effortless as the lifestyle itself, leaving owners responsible for only electricity and cable/internet. The thoughtfully designed floor plan features two spacious bedroom suites, each with its own private bathroom and generous walk-in closet, creating the comfort and convenience of two true primary suites. An in-unit laundry room adds to the ease of everyday living. Beyond your front door is where Washington Square truly sets itself apart. Take in sweeping city views from the eighth-floor rooftop terrace with grilling stations, host friends in the beautifully appointed resident lounge complete with a full bar, stay active in the fitness center, or enjoy the convenience of your assigned, covered parking space featuring a heated car wash bay and vacuum station. Pet owners will appreciate the rooftop dog relief area and dedicated dog wash station, while the included private storage unit offers plenty of space for seasonal items and more. The secure, welcoming lobby creates an impressive first impression, and with restaurants, coffee shops, entertainment, live music, and the Washington Pavilion just steps away, downtown Sioux Falls becomes an extension of your home. Lock the door. Leave town. Meet friends for dinner downstairs. Catch a show, grab coffee around the corner, or watch the sunset from the rooftop. This is the maintenance-free, amenity-rich lifestyle that makes Washington Square one of downtown Sioux Falls' most desirable places to call home.
