A hidden retreat in the heart of Old Naples. Tucked away at the end of a quiet, dead-end street shared by just four properties, this exceptional lakefront residence offers a rare combination of privacy, tranquility, and proximity to Naples' most celebrated destinations. Custom built in 2013 and offered for sale for the very first time, the home is thoughtfully set back from the street, creating a secluded sanctuary just moments from the beach, Four Seasons, and the charm of downtown Naples. Designed for both gracious entertaining and everyday comfort, the residence features four en-suite guest bedrooms, a spacious primary suite, private office, and additional loft area. The outdoor living experience is equally captivating, with a covered lanai, pool and spa overlooking the peaceful lake, a charming koi pond, and private dock. One of the property's most distinctive features is its detached guest suite, complete with a bedroom, full bathroom, and kitchenette. This thoughtfully designed accommodation offers exceptional flexibility for visiting family, extended guests, or live-in staff, providing privacy and independence from the main residence. With only four properties along this secluded stretch of Third Street North, opportunities to own in this intimate lakefront setting are exceptionally limited. A truly unique offering, combining the serenity of a private waterfront retreat with the convenience of Old Naples living.
