    What's special

    A rare offering of Cambridge history, the Charles Valentine House, circa 1837, is a classic piece of Greek Revival architecture in the leafy heart of Cambridgeport. With elegant lines and beautiful period detail, it gained 21st-century comfort and convenience during a restoration to exacting standards by the noted contractor Charlie Allen in 2006. An attached single-family home with a columned front porch, it features 6 bedrooms, 4.5 bathrooms, six fireplaces, abundant space and skylights, and off-street parking for 4+ vehicles. The expansive backyard with a beautiful garden and deck for entertaining sets this property apart. An added delight: the fully finished basement with a private entrance is perfect for a rental unit, au pair suite, or the dream basement. Enjoy a walk score of 99 with close proximity to MIT, Harvard, Central and Kendall Square, this is the ideal home in the city!

    This property is off market, which means it's not currently listed for sale or rent on Zillow. This may be different from what's available on other websites or public sources.
