your best bet is probably quincy or the \'nice\' area of dorchester and south boston.
i don\'t do the south shore though, so i\'m not super familiar.
JP is also a good option but i\'m not too sure how close that is to 93.
but i\'d never live anywhere other than arlington/cambridge/somerville/medford again (while i rent)
why only those neighborhoods?
well, i should clarify - west cambridge/somerville. east it can be shady.
its safe, lots of stuff to do - not just nightlife either - public transportation is available (within 2 blocks i have 7 different buses) AND having a car is easy, HUGE variety of eats, i can ride my bike, most of those areas are away from student ghetto and more young professional, and if you look hard enough, it\'s affordable. the only down side is arlington doesn\'t have non restaurant bars but i\'m ok with that.
i\'d consider going back to newton/watertown and maybe even waltham.
allston to me is fun, but it just has this student ghetto/dirty feel to it, plus even though i like to party from time to time i don\'t really want it in my face 7 days a week.
