Dive into coastal elegance at The Portside, an architectural award winning maritime-inspired residence nestled in the vibrant heart of South Beach. This expansive 1+ bedroom condominium flows like the tide, with an open-concept design bathed in natural light and framed by tranquil water, bridge and city vistas. The beautifully remodeled kitchen, adorned with stainless steel appliances, rich cedar cabinetry, and sleek granite countertops spills effortlessly into a generous living space, perfect for entertaining or unwinding after a day by the bay. Dramatic, curving windows in the main living area capture sweeping, ever-changing views like a living seascape. Thoughtfully updated throughout, the home features custom built-ins, designer lighting, custom closet, warm hardwood floors, plush Berber carpet, and the convenience of an in-unit washer and dryer. A versatile bonus den offers the ideal retreat for a home office or a welcoming harbor for overnight guests. The Portside itself is a sleek streamline modern vessel, complete with 24-hour security, attended lobby, secure mail room, manicured grounds, earthquake insurance and a resort-style heated pool and spa overlooking the Bay along with 3 gyms. Bask on the sun deck, recharge in one of the three fitness centers, and enjoy the ease of storage and assigned leased parking. Perfectly positioned amid South Beach's most sought-after destinations, you're moments from the Embarcadero's scenic waterfront, South Beach Marina, Market Street, and the Ferry Building's vibrant marketplace and farmer's market. Catch the excitement of game day at nearby stadiums, or take advantage of close proximity to UCSF and the Financial District's dynamic tech corridor. With seamless access to freeways, MUNI, BART, and Caltrain, the entire Bay Area is within easy reachmaking this home a true harbor in the city, where urban energy and waterfront tranquility meet.
