You cannot recreate this—location, views, and private deck like this simply don’t exist elsewhere. For the first time in 19 years, the crown jewel of The Esplanade is available—a rare penthouse with sweeping, unobstructed views of the Charles River and Boston skyline, anchored by an expansive private deck seemingly suspended above the water. This coveted corner residence offers privacy and single-level living with seamless indoor-outdoor flow, perfect for elegant entertaining or tranquil living. Walls of windows frame the views, while the chef’s kitchen with brand-new Thermador appliances opens to sunlit living and dining areas with cherry floors, granite finishes, fireplace, and custom built-ins. The spacious den leads to an oversized primary suite with stunning views, walk-in cedar closet, and marble bath. Sound systems, electric awning and skylight shades, irrigation, 2 oversized deeded garage spots, and more. Full-service 24/7 concierge building w/pool, sauna, and fitness center.
