2550 HARBOURSIDE DRIVE UNIT 333 LONGBOAT KEY FL 34228 | MLS #A4708474

Set within the gated BAY ISLES community, this MARINA BAY residence offers a rare combination on Longboat Key: the scale and privacy of a single-family BAYFRONT home with the ease of condominium living.

Spanning approximately 3,000 square feet with three bedrooms and two-and-a-half baths, the residence feels expansive and closely connected to Sarasota Bay. Floor-to-ceiling glass across the main living areas and primary suite frames mature mangroves and coastal trees, creating a peaceful, park-like setting with filtered morning light and bay views.

Nearly 400 square feet of screened lanai space extends the living area outdoors, while a second west-facing balcony serves the guest bedrooms and captures afternoon light and evening skies.

The primary suite offers bay views from bed, terrace access, dual walk-in closets and a spacious bath with soaking tub, dual vanities and glass-enclosed shower. The kitchen features quartz countertops, Sub-Zero refrigeration, generous prep space, a wet bar with beverage refrigerator and a built-in desk nook. A large walk-in laundry room adds substantial workspace and storage.

Freshly painted with new carpeting, the residence also features two-zone air conditioning with new condensers installed in 2025, two hot-water tanks with flood-stop protection, air-conditioned storage, assigned garage parking and exceptional closet space.

Marina Bay is known for attentive management and a well-run homeowners association, with an experienced on-site manager and amenities including a fitness center, tennis and pickleball courts, heated resort-style pool, EV charging and car-washing facilities. The building’s new roof was completed in 2025, and the community is pet-friendly.

Longboat Key Club Marina is immediately adjacent, while Publix, CVS, banking and the post office are just blocks away, creating a genuinely walkable daily rhythm uncommon on Longboat Key.

Ownership also includes access to the private Bay Isles Beach Club, a gated Gulf-front retreat with parking, pavilions, grilling areas, restrooms and sunset seating. Optional membership at the nearby Longboat Key Club offers golf, tennis, spa and wellness amenities, and waterfront dining.

For buyers seeking the comfort and proportions of a home without the maintenance of one, this Marina Bay residence offers an uncommon balance of space, privacy, nature and convenience.
