Ahh, you didn't mention that in your pre-requisites. Culture fix? How about Suffolk county on the Island? Only an hour train ride to the city.
Lived a couple of years there... Lovely city... Very peaceful place to live... Great Airport... Access to whole Europe and the US easily... If you don't mind a heavy dose of communism, it's a great choice... Und die deutsche Sprache ist nicht so schwierig zu lernen... Ich habe selbst in einem Jahr sie gelernt.. Und meine Muttersprache ist Portugiesisch, deswegen wird es wahrscheinlich leichter für dich...
Good point. I would say, in no particular order -- vibrant ex-pat community -- active cultural life (although I have considered Costa Rica, which appeals to the hiker in me) -- competent medical facilities -- reliable infrastructure -- overall value (which eliminates London, for example) I should add that my tax load in Massachusetts is substantial. That's also a factor.
