About this home
3240 GULF OF MEXICO DRIVE UNIT B504
Welcome to Portobello, a Gulf to Bay community on mid Longboat Key where residents enjoy their own private beach access just across the street and a bayside dock right outside the door. This beautifully remodeled, turnkey furnished fifth floor condo overlooks the quiet waters of Cranes Bayou, positioned to catch soft morning light while the terrace stays comfortably shaded through the afternoon. Inside, the open floor plan is filled with natural light and finished with new laminate wood flooring, crown molding, plantation shutters, and new light fixtures throughout. The updated kitchen offers stainless steel appliances, custom white cabinetry with crown molding, under cabinet lighting, and a breakfast bar that opens to the dining area. The split bedroom layout is ideal for hosting guests. The oversized primary suite features its own water views, space for a king sized bed, an oversized walk in closet, and an en suite bath with a smart split sink and shower design, while the equally spacious second bedroom sits beside a fully updated second bath. A sleeper sofa in the living room allows the condo to comfortably sleep six, and an in unit washer and dryer adds everyday convenience. The full length screened terrace spans the entire width of the unit and is accessible through new impact sliding doors from the living room and both bedrooms, so the water view follows you from room to room. Portobello's amenities complete the picture. Residents enjoy a heated pool with tennis courts, a fully renovated recreation room, kayak and canoe storage with a launch area, and a dock and walkway for fishing or docking your boat for up to two days. A bayside picnic area with a gas grill and umbrella tables sits near the kayak launch, perfect for sunset cookouts by the water. Just across the street, Portobello's private beach access puts the Gulf and its sugar sand shoreline a short stroll from your door, complete with a beach shower for rinsing off after a day in the sand. Each unit has its own extra ground floor storage locker, and the freshly painted, recently inspected building is centered on a lush tropical courtyard with a fountain, surrounded by beautifully landscaped grounds with paver parking. Condominium fees include water, sewer, trash, and basic cable. You are also just moments from everyday shopping and convenience at the Shoppes of Bay Isles, home to a Publix, CVS, and more, all without ever leaving the island, while St. Armands Circle and downtown Sarasota are an easy drive down the Key. With upgraded windows and doors, furnishings, appliances, and modern baths already in place, this is a Longboat Key retreat ready to enjoy from the very first day. Come experience it for yourself. **THIS PROPERTY QUALIFIES FOR A 1% LENDER INCENTIVE IF USING PREFERRED LENDER. INQUIRE FOR MORE DETAILS.**

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
