This stunning, light-filled penthouse unit sits well back from the street, facing southwest and spanning the top floor of its prewar building. A dramatic entry stairway leads up to a skylit key hall, ringed in arched brick walls that open to a living/dining area bookended by fireplaces. The kitchen, also with skylight, has a decorative tile backsplash, granite counters, and stainless steel appliances. The nearby corner bedroom is adjacent to a recently renovated tiled bathroom with a striking tambour ceiling, while the main bedroom has a delightful full bathroom with circular soaking tub and custom cabinetry. The third bedroom (recognized by the city) is currently being used as a home office, with built-in desk and cabinets, and a ladder leading to a skylit loft. From the loft, one can access the roof, rights to a section of which are deeded to the unit. There's also a large shared back yard, with the shops, restaurants, T stops, and attractions of Harvard and Central Squares nearby.
