About this home

474 square feet of very good decisions. Tucked on the second floor of a handsome brick building right on Mass Ave, across from Porter Square and a short stroll to Harvard Law, this sun-lit one-bedroom puts you at the center of Cambridge's most beloved urban village - steps from the red and commuter lines, Bagelsaurus, Giulia, Yume Wo Katare, Porter Square Books, and more of the neighborhood energy that makes this stretch of Cambridge so hard to leave. Compact but never cramped: an efficient layout with a full kitchen, a tiled bath, generous closets, and windows that frame the lively street below. In-building laundry, a common yard, and a Zipcar station around the corner round out the package. It's the kind of place a Harvard or Lesley affiliate claims as their city anchor, a parent invests in for a child/student, or a savvy buyer quietly adds to a portfolio. Whether you're putting down roots, procuring a pied-à-terre, or investing, this little gem punches well above its weight.
