Welcome home to this bright and beautifully updated 4-bedroom, 2.75-bath residence tucked into a quiet cul-de-sac in mid-island Mercer Island. At 3,180 square feet on a generous 15,061 square foot lot, this home offers space to spread out both indoors and out. Fresh paint and new carpet throughout give the interior a crisp, move-in-ready feel, while abundant storage keeps everyday life organized. Western exposure fills the home with natural light all day long. The large downstairs has both a huge rec room and bonus room that could be an office, gym, or media room. Step outside to expansive patios and decks designed for seamless indoor-outdoor entertaining, overlooking a large, level lawn perfect for play and gatherings. Garden enthusiasts will love the raised garden beds, and a dedicated children’s play area makes this a true retreat. An irrigation system keeps the landscaping lush with ease. This is quiet cul-de-sac living at its best — close to everything Mercer Island has to offer, yet tucked away in your own private oasis.
