Welcome to 3626 6th Street S, a classic white brick Cape Cod in Arlington's Alcova Heights neighborhood, offering over 2,000 square feet across three levels. A stone walkway leads past mature hedges and a gabled dormer roofline to the front porch, setting the tone for the character throughout.Inside, the main level opens with a living room centered on a wood-burning fireplace, flowing into a completely renovated kitchen (2024): custom KraftMaid cabinetry, quartz countertops, new tile flooring and backsplash, a farmhouse sink with a professional-grade faucet, and a full GE Café appliance suite, including a French-door refrigerator, slide-in gas double-oven range, smart dishwasher, and built-in microwave drawer, all anchored by a custom breakfast nook. Two bedrooms and an updated full bath complete the main level. Just off the living room, a screened-in porch offers a shaded spot to unwind, framed by the home's mature landscaping.Upstairs, the largest bedroom features an abundance of natural light from a skylight and offers a private escape from the main living area.The finished lower level features a family room, a bonus room, a full bath, and custom-built dog kennels.Outside, the backyard delivers generous space for the area: a paver patio for entertaining, a flat lawn framed by mature trees and flowering crepe myrtles enclosed by a fenced yard with room to garden, play, or simply spread out. A detached garage adds additional storage and utility, and the size of the lot may also offer potential for an ADU.Recent system updates include a 200-amp electrical service upgrade, a new Daikin AC condenser (2025), new Provia windows on the main level (2024), and a new sliding patio door and steel entry door (2024).Columbia Pike's shops and restaurants, including Harris Teeter, Pho Saigon, L.A. Bar & Grill, Pupuseria Sofia, and Orangetheory Fitness, are all within walking distance, while Arlington Boulevard, I-395, and Columbia Pike keep the commute into Washington, D.C. effortless. This Cape Cod stands as a rare, move-in-ready find in one of Arlington's most convenient neighborhoods.
