The Nathan Mayhew house offers a gracious family gathering place for the ages, opposite Owen Park with views of the town beach and beautiful Vineyard Haven harbor, legendary for its flotilla of wooden boats.   The 1840s Greek revival classic has a rich recent history as a writers' year round family home, a successful luxury B&B and a lucrative summer rental property.  Seven gracious bedrooms, all with ensuites, most with water views, and large open plan entertaining areas are complimented by a recently renovated, spacious country kitchen.  Walking distance to the ferry, yet out of the town bustle, this grand yet comfortable home offers an attractive, low maintenace garden with lovely mature plantings, a two-car garagewith loft, and up to four additional parking spaces.  The recently reduced price makes this an outstanding opportunity to own one of the true gems of Vineyard Haven.
