About this home

Transit-oriented living at its best: a two-minute walk to Maverick Square's Blue Line station (3 minutes to Aquarium, 5 to State Street), with the Water Taxi at Stop 66, ReelHouse, and a five-minute drive to the airport all close at hand. Pet friendly, with amenities including 24/7 concierge, a fitness center with flex studio, a harbor-view resident terrace with grills and fire pits, a golf simulator, and private storage on the same floor as the home. Curated for sophisticated city living, this turnkey residence features rich hardwood floors and a bright, sun-drenched layout with scenic water views from both the living room and bedroom. Extensive windows frame the freshly painted open living space, which flows seamlessly into a gourmet kitchen centered around a waterfall island with premium stainless steel appliances. The tranquil bedroom is bathed in natural light, complemented by a spa-inspired bath in contemporary stone, in-unit laundry, and additional storage — completing this luxury home.
