Within 911 sq. ft of one-bed + den living, soaring ceilings and floor-to-ceiling windows frame sweeping city and river views. The chef-ready kitchen features quartz counters, sleek wood cabinetry, and stainless appliances—perfect for day-to-night living. The flexible den can serve as a guest room, home office, or creative nook. The bathroom, remodeled in 2020 by Northfork Design, is a spa-like retreat complete with marble walls, porcelain hex-tile floors, luxe fixtures, and warm wood storage. Step out onto the private balcony for serene city-perched moments. Located just blocks from Lechmere, Cambridge Crossing, Boynton Yards & East Cambridge, you’re also minutes from CambridgeSide Galleria, the Charles River & Kendall Square.
