Built in 1873

A rare single-family home on a quiet, tree-lined street in the heart of Cambridge, offered for the first time in over 80 years. This cherished home was renovated to the studs in 2013 — every system upgraded, central air added, and the first level reimagined with an open floor plan built to maximize the space. The first floor offers a kitchen with natural stone counters, stainless appliances, and a peninsula that seats company while you cook, flowing straight into the open dining and living areas. A half bath and laundry round out the first floor. Upstairs are three bedrooms with hardwood floors and a full bath. Out back is what's rare to find at this price: a fully fenced yard with a brick paver patio and garden beds — a true urban oasis. All this in a vibrant neighborhood with an updated park at the end of the street, convenient to Inman, Union, Central, and Kendall Squares, the Red Line at Central, and the Green Line at Union Square.
