I always follow Twain's advice
“Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.”
I dunno, if I came down here without ever seeing it
to live, expecting the Paris of South America, couldn't find a job or local friends or get involved in the culture and blew 15k in a few months, then headed back home because I was dry $ wise, I would be pretty disappointed I had ever done it!! (its a possibility isn't it?).
But, hey Tim as long as you realise this aint Paris and it isn't
that cheap and that finding a job mighn't be easy, nor might Argentine Spanish I think you'll be fine. There is lots to love and lots of fun to be had. Bring plenty of USD cold hard cash here to change on Florida, if your spanish is crappy enrol in a Spanish school (see recommendations on this site, for eg) to get the ball rolling on Spanish and a social life.
But man, please don't just close yourself to BA, there is so much to see out of the CF bubble, both in this country and the continent that it would be a shame to blow all of your money within a 5km radius! If you don't have a job or money getting in the way (mind you, the interior of the country is usually cheaper, bar some of the south) then why not spend a good amount of time in Cordoba, Mendoza, Tucumán, Salta etc. The people are entirely different (well note entirely even though they might tell you
, but quite different), the life is often another rhythm (with
la siesta) and you will get a better taste of more traditional Argentine culture which often is watered down in CF.
Good luck!
