About this home
This is a home full of charm, with hardwood floors and a mantled stone fireplace anchoring the living space. The kitchen carries rich hickory cabinetry with all appliances included, and the bathroom has been freshly renovated with a custom tile surround.A newer gas furnace, updated plumbing, and triple-pane, energy-efficient windows keep things running smoothly year-round. Sliding glass doors off the dining room lead to a large covered patio, made for grilling and entertaining through the long summer nights. Beyond it sits a massive, fully fenced backyard, the kind of private outdoor space that's rare to find this close in.Location does the heavy lifting too. You're minutes from Angle Lake and Marina Beach, with nearby parks and the Angle Lake light rail station for an easy ride into Seattle. Quick freeway access puts your commute on easy mode, with Sea Tac Airport, shopping, and dining all close by. Real character inside, real space outside, and a real neighborhood to back it up.
