2550 HARBOURSIDE DRIVE, #333, Longboat Key, FL, 34228 | $1,495,000

Set within a living canopy of mangroves and coastal trees, this BAYFRONT residence invites a more immersive relationship with Sarasota Bay—where filtered light, birdsong, and gentle water movement define everyday living.

Behind the gates of Bay Isles on Longboat Key, this approximately 3, 000-square-foot waterfront residence offers the ease and scale of a single-family home with the security and convenience of condominium living. With three bedrooms and two-and-a-half baths, the layout lives expansively, enhanced by abundant storage and thoughtful separation of living spaces.

Floor-to-ceiling glass sliders in the main living areas and primary suite face east, capturing peaceful sunrise light over Sarasota Bay in a setting best described as park-like waterfront—where mature coastal trees frame the water, creating a serene, private “treehouse” ambiance. Boats glide through the mangrove preserve and lagoon toward open bay waters, accompanied by birdsong and rustling leaves. Two balconies extend the living space outdoors, including a nearly 400 sq ft screened lanai ideal for relaxed coastal living. The primary suite features bay views from bed, terrace access, dual walk-in closets, and a spa-like bath with a freestanding soaking tub, dual vanities, and a glass-enclosed shower.

The second and third bedrooms share access to a west-facing balcony, offering sunset light and cross-breezes.

The kitchen is both functional and social, featuring quartz countertops, a Sub-Zero refrigerator, generous prep space, a built-in desk nook,  mini-fridge and wet bar—well suited for entertaining or casual mornings. A dedicated walk-in laundry room adds practicality with a butcher-block workspace, hutch, and tool cubby.

Comfort and peace of mind are prioritized with two A/C zones, new condensers (2025), and two hot water tanks (2021) equipped with a flood-stop device. Brand new carpet and paint.

Additional highlights include air-conditioned storage, one assigned garage parking space, and exceptional closet capacity—five linen closets, three pantry closets, and three walk-in closets.

Residents enjoy on-site management, a fitness center, tennis and pickleball courts, a heated resort-style pool, car washing area, and EV charging stations. The building features a brand-new roof completed in 2025. Pet-friendly.

The location is as compelling as the home itself: secure, serene, and walkable. Adjacent to the Longboat Key Club Marina, and just blocks from Publix, CVS, the post office, and banking, this location allows for a genuinely walkable daily rhythm—rare on Longboat Key.

As part of Bay Isles, residents also enjoy access to the Bay Isles Beach Club, a private Gulf-front retreat with gated parking, pavilions, grilling areas, restrooms, and seating for sunset views. Deeded beach access ensures a premier spot on the sand. Membership to the nearby Longboat Key Club is available, offering championship golf, world-class tennis, a full-service spa and wellness center, waterfront dining.
