Wide-water views and direct access to Mariners Lagoon set the stage for a lifestyle rarely found on the Peninsula. This waterfront attached single-family home offers a front-row experience to water skiing, kayaking, and paddleboarding, right from your own private dock. The single-level design is bright and inviting looking out to the water from almost every room and connecting to a large deck with stairs down to boat launch. Beautifully maintained and ready to enjoy, this home has a new primary suite bath, all new plumbing, and more. Plus, this well-appointed community has resort-style amenities that include pools, pickleball, a fitness center with sauna, and boat storage area. One of the Peninsulas best-kept secrets, this home offers everyday ease just minutes from shopping, dining, and the Bay Trail.
