Waterfront luxury living at The Mark. Completed in 2020, this spacious one-bedroom plus den residence pairs sophisticated design with exceptional privacy, sharing its section of the floor with just one neighboring home. The open-concept kitchen and living area is anchored by a striking waterfall Silestone island and features sleek cabinetry, Bosch appliances, wide-plank flooring, abundant natural light, and a partial water view. The bright bedroom comfortably accommodates a king-sized bed, while the versatile den is ideal for a home office, nursery, or guest space. Custom-fitted blinds throughout the living room and bedroom, an in-unit washer and dryer, generous closets, and a private storage unit conveniently located on the same floor complete the residence. The Mark delivers a true full-service waterfront lifestyle with 24/7 concierge, a state-of-the-art fitness center, resident lounge, golf simulator, pet spa, electric vehicle charging stations, and a spectacular harbor-view terrace with grilling stations, fire pits, and panoramic views of the Boston skyline. Rental parking is available nearby. Set directly along the East Boston waterfront in Jeffries Point, the home is moments from ReelHouse, La Tavernetta, waterfront parks, the water taxi, and Maverick Station, offering MBTA blue line access to Downtown Boston in just two stops and effortless proximity to Logan Airport. This is city living with a waterfront address and resort-style amenities.
