About this home

Welcome to one of Isla Key’s premier waterfront view opportunities. This desirable 3-bedroom, 2-bath end-unit condo offers 1,255 square feet of bright, comfortable living space and the kind of open, unobstructed balcony view buyers hope to find. From the moment you enter, wide sliding glass doors frame expansive water views and draw the coastal setting right into the home. The open living and dining area flows naturally to the private waterfront balcony, creating an ideal layout for relaxing, entertaining, or simply enjoying the scenery. The spacious kitchen features warm wood cabinetry, granite countertops, stainless steel appliances, and a breakfast bar connection to the main living space. Thoughtful updates add to the home’s everyday comfort, including wood-look flooring, generous natural light, and a beautifully tiled walk-in shower with built-in niche and bench. The end-unit position enhances the sense of privacy, with no direct balcony view into neighboring units and a standout vantage point over the water. Whether you are looking for a full-time residence, seasonal retreat, or low-maintenance waterfront escape, this condo delivers the lifestyle so many buyers seek in St. Petersburg. Isla Key is known for its resort-style waterfront setting on Boca Ciega Bay, offering a heated waterfront pool, spa, tennis and pickleball courts, grilling areas, kayak and water access, beach-style lounging areas, and beautifully maintained grounds. Located along the Pinellas Bayway, you are just minutes from St. Pete Beach, Fort De Soto, Isla Del Sol, downtown St. Petersburg, restaurants, shopping, and convenient airport access. With its exceptional water view, private balcony setting, end-unit location, and sought-after Isla Key amenities, this condo is a standout opportunity to enjoy the Florida waterfront lifestyle.
