Perched atop one of Avon Hill's most admired brick courtyard buildings, this sun-filled penthouse corner residence combines classic Cambridge character with thoughtful updates and skyline views. South-facing and filled with natural light, the home features hardwood floors, tall ceilings, oversized windows, and a wood-burning fireplace. The renovated kitchen offers granite countertops, custom cabinetry, under-cabinet lighting, stainless steel appliances, and subway tile backsplash, while the updated bath includes a soaking tub and contemporary finishes. Enjoy sweeping city views from the shared roof deck, plus the convenience of laundry facilities, bike storage, professional management, and heat and hot water included in the condo fee. Recent association improvements include major plumbing infrastructure upgrades serving Unit 18, replacement of the building boiler, and replacement of hot water systems. Ideally located near Harvard & Porter Sq, the Red Line, restaurants, shops, & parks.
