I live in Cordoba...a good place to do business is a tad broad. I teach english, and based my reading of this site, there are more and better paying native english teacher positions in Cordoba than in BA, due to the relative lack of native speakers.
What type of business are you considering?
The surrounding towns in the Sierras are nice for mountain biking, trekking, camping, rock climbing, and most favorite of all Argentine outdoor activities, sitting by the river and drinking mate.
Cordoba though, is a far far cry from the international metropolis that is Buenos Aires.
