The small but growing residential base in Boston's downtown core is a welcoming bunch of pioneers, as the arrival of an upscale supermarket has added to the appeal of this bastion of urban living. The charms are many-easy transit to all parts of the city and beyond, plus a short walk to the theater district, Chinatown, and the Financial District. Bordered by the Boston Common, historic buildings like the Old State House rub elbows with shiny new residential towers for a uniquely Bostonian vibe.
