About this home
Welcome to 100 Boatswains Way #510, a spectacular top-floor corner penthouse at Admiral’s Flagship Condominiums, where sophisticated condo living near the city meets the serenity of 19+ acres of waterfront open space. Perched high above Chelsea’s coveted Admiral’s Hill neighborhood, nestled on a private way, this sun-drenched residence offers dramatic vaulted ceilings, exceptional open space, a private 14-foot balcony, and deeded garage parking. In 2025/2026, the seller invested $25K+ in improvements, creating a beautifully refreshed, truly move-in-ready home. The renovated 2023 kitchen features sleek quartz countertops, custom cabinetry, stainless steel appliances and brand-new flooring. Both bathrooms were completely renovated in 2023, including a beautifully appointed primary bath with walk-in shower with custom tile. A new custom designed coffee niche/bar with coordinating cabinetry was thoughtfully added to the dining area — perfect for morning coffee or evening entertaining. The expansive living area is flooded with natural light and framed by dramatic vaulted ceilings. Both bedrooms are exceptionally spacious, featuring new hardwood flooring, new custom blinds and generous closets. Additional conveniences include in-unit laundry with stackable washer/dryer and additional deeded storage. Apprx 2023 - The HVAC system was replaced. In 2026, the association replaced the main cooling towers. - Need some fresh air? Step outside to your private, sun-splashed balcony, accessible from both the living room and primary suite—the perfect place to start your day, entertain friends or simply unwind and watch the sunsets. Outdoor enthusiasts will love having acres of waterfront open space a short distance beyond their front door, at The Mary O’Malley State Park. Enjoy scenic waterfront trails, running paths, tennis courts, expansive green space and a playground. ADD a well-managed association with LOW condominium fees that include HEAT & HOT WATER, a private inground swimming pool, private evening security and association-wide security cameras, and you have a truly rare combination of LOCATION, VALUE, LIFESTYLE & PEACE OF MIND.
