Just spent 2 months in Alta Gracia outside of Cordoba. Currently in Villa Carlos Paz. Both have quality internet, something I found a bit lacking in Jujuy province. VCP at 75,000 is a very developed small city and very touristy. Alta Gracia is 50,000 and feels like a big town. However it has good amenities for its size and is only 22 miles from Cordoba. People are nice enough in VCP but I found Alta Gracia to be a cut above in friendliness. Haven't seen all of Argentina yet but suspect in these smaller cities no matter where you go the people are going to be great. Just a matter of deciding if you want plains, coasts, low lying mountains, or jaw dropping mountain scenery.
