Rarely available upper-level duplex in the heart of Union Square — fully renovated and move-in ready for September 1st. This sun-filled 4-bedroom, 2-bath home delivers the space and finishes renters in this market rarely find together: a chef's kitchen with oversized center island, granite countertops, and stainless steel appliances; in-unit washer/dryer; a private deck; and two dedicated parking spaces. Location is unmatched. The Union Square Green Line stop is steps away, Harvard is 1.2 miles, and Porter Square is 1.3 — putting the best of Cambridge and Somerville's dining, café culture, breweries, and universities within easy reach on foot or by T.
