Another vote for Buenos Aires, try an AirBnB in the neighborhood of Palermo Soho, we have done this several times; there's great access to public transportation (cheap and excellent), the exchange rate is great for American tourists now, and if you get homesick you'll have Starbucks, Pain Quotidien, and a bunch of similar chains in the area. The only downside is that it will be winter there, but that only means 50s or 40s in a bad day (it doesn't snow over there). You'll love it. You could also do day or weekend trips to Uruguay and catch a plane to Brazil, Chile or Peru...really worth it.
