Right in the heart of it all is this sweet townhome that lives like a single family home! Welcome to 21879 Shallow Rock Square, with two assigned parking spaces, right out front. Enter the two-story foyer, and you will see right away that this home has an entertainer's flow. Step down into the most charming and light-filled eat-in breakfast area & kitchen, with stainless steel appliances, a breakfast bar, and wood-look flooring. This leads into a dining room (or office area) and a gracious family room with a wood-burning fireplace and crown molding. Head out to the rear yard with a paver patio, all enclosed by privacy fencing. Back inside, and up the steps to the upper level, featuring three gracious bedrooms - really, you will not believe the sizes! The Owner's en suite bathroom has an enormous shower with dual benches, and a dual vanity! The finished basement is below grade, and will be a crowd-pleaser, for sure. Within approximately 800 sq ft (estimated) is a rec room, den, full bathroom, laundry/utility area, and under-stair storage. Located so conveniently to Dulles Airport, the metro, Reston, Herndon, Ashburn, etc., you have all the daily needs covered within a few minutes' drive. You also have all the recreational activities your heart desires, just around the corner: Algonkian Regional Park on the Potomac River with golf, a waterpark, and hiking, Claude Moore Park nature trails and rec center, and an indoor rock climbing center, just to name a few! The Reston Town Center and Dulles Town Center offer amazing shopping and dining experiences.
