Older Bostonians might still derisively call it "Slummerville", but today that tired old moniker couldn't be further from the truth. Packed with upwardly mobile professionals and longtime residents, Somerville is often voted an "All-America City" and the best-run city in Massachusetts. It would seem civically engaged folks can achieve uncommon results; and Somerville fosters an environment of cooperation like no other. Its 81,000 residents (2020) are quick to enjoy the fruits of their artistry, and you'll find top notch options for dinner, drinks, and dancing all in abundance within Somerville's borders. Lurking just to the south, big brothers Boston and Cambridge provide options and opportunities for many of Somerville's creative class residents.
