Enjoy all that Old Town has to offer in walking distance from this gorgeous home...one block to the water and a few blocks to King St. A cheerfully landscaped front yard welcomes you home! The entertaining flow is perfect inside and out of this charming end-unit townhome. Upon entering this light-filled home in the heart of Alexandria's Historic District, you'll first be impressed by the luxurious surroundings and then excited at the sights & sounds of your own private, heated swimming pool. The foyer leads to an open and bright entertaining area highlighted by a large living room with a wood-burning fireplace and French doors to the pool patio area. A wet bar with a beverage frig and a powder room adds an element of convenience. BBQs are made easier when you can connect your grill directly to the natural gas line on the patio and enjoy extended summers in the terraced gardens, relaxing alcoves, and heated pool. On the main level is a cozy TV room anchored by a gas fireplace flanked by built-in cabinets and connected to the kitchen via a breakfast bar with seating for approximately four people. The sun-drenched kitchen has been thoughtfully updated with a Viking stove, white cabinets, a custom backsplash, and a refrigerator with cabinet panels to match. Pocket doors provide privacy from the dining room which can easily accommodate seating for 12 or more guests. The upper level boasts spacious bedrooms, including a master suite that spans the entire third level and has a gas fireplace for ambience. The bathroom suite feels like a private spa retreat, complete with a steam shower, jetted soaking tub, water closet with a bidet, double vanities, and a linen armoire. Upstairs, there are two additional bedrooms with a shared bathroom. Features found throughout the home include custom trim & wainscoting, surround sound system, large windows, privacy plantation shutters, hardwood flooring & stairs, and recessed lighting. With the help of AI, photos have been included to help visualize a different color wall paint in the living room and primary bathroom. Separate HVAC systems with one servicing the lower 2 floors and the other for the upstairs bedroom levels. Most recent updates include the electrical panel, one HVAC system, and the exterior trim repainted several years ago. Private, dedicated parking is available via an attached garage and a private parking space, with additional storage available in the garage and an entrance. Foodies will love the proximity to a variety of dining options such as Ada's on the River, Hummingbird Bar & Kitchen and Chadwick's to name a few. Nature lovers can explore the trails, bike paths, or hop on a boat to view the monuments or attend harbor events. Uniquely local Scottish Christmas Walk Parade, Torpedo Factory events, and Phantoms of the Potomac Walking Tours are a short list of not-to-be-missed events. Oh yes... there's also a ton of historic sites to see and experience along the way. Living in Old Town provides easy access to everything you need and more. You are only 1 block from the water, shopping & dining. Transportation options include a free shuttle, several Metro stations, all major highways and National Airport. 303 S Union St is a remarkable home smack in the middle of a historic City.... an ideal place to call home!
