Cambridgeport. A stone's throw from Central Square and the Red Line, MIT, Harvard, and with easy access to HBS, downtown Boston, and Longwood Medical, 12B Watson is a commuter’s dream! This attached four bed/three and a half bath single family is a peaceful retreat from the nearby hustle. The living space is intimate and inviting, with seamless flow between kitchen, dining and living rooms, while the second level includes two large bedrooms, a full bath, and laundry. An expansive primary suite and private deck complete the third level. With direct exterior access and a full bath, the lower level's fourth bedroom offers tremendous flexibility as a teen lair, au-pair suite, or short-term guest area! Outside, the back garden is serenely surrounded by an ivy-clad fence, offering the perfect setting for gardening or al fresco dining. Deeded parking seals the deal, allowing one to ditch the car and live a true urban lifestyle on bike or foot! Seller welcomes offers with requests for buyer agent compensation.
