About this home

Set in a distinctive Greek Revival building in the much-sought-after Riverside neighborhood, this two-level penthouse is just minutes from Harvard Square and the Charles River. A private entrance leads to a sun-filled, open-plan living and dining area, with near-floor-to-ceiling windows and direct access to a private deck. The tucked-away kitchen has been newly renovated with quality appliances, quartz countertops, and ample painted cabinetry. The main level also features a comfortable bedroom with an ensuite bath. Upstairs, the two additional bedrooms have high ceilings and exposed wooden beams, while a second updated bathroom includes a large skylight. Adjustable electric baseboard heating, oak hardwood floors, in-unit laundry, two parking spaces, and an exclusive-use front patio add to the appeal. Enjoy easy access to vibrant dining, local shops, the MBTA Red Line, Whole Foods, and Trader Joe’s.
