Located on a rare find 40 foot lot. A 40 feet wide lot offers significantly more space, light and private parking (a coveted premium on the Island). Currently offers parking behind the garage and a spot alongside the garage. Easy access to the home with alley access off Marine Dr. just over the Bridge. This Balboa Island mid-century beach house takes advantage of its position, with views toward the Bay and a constant reminder of how close you are to the water. It’s an easy access to the Shoreline, Marine Avenue shopping, Dining and fun. Balboa is everything that makes Newport Beach what it is—but far enough removed to feel quiet and livable.
