I am sure you have to visit Buenos Aires, main destination!!
Besides that Iguazu, Calfate, Ushuaia & Puerto Madryn as a basic itinerary
and then if you want to make something more special, add
Mendoza as a wine region which is really interesting
besides that, visit the north in Salta which is also fantastic

Go to the San Telmo street fair in Buenos Aires. It happens every Sunday and is a must see. I also loved la feria en la plaza Francia. It happens every weekend and has great vendors. I bought some fantastic art there. They also have bands play there in the evening. The cemetery in Recoleta is huge and very interesting to see. I also recommend taking a tango lesson while there or seeing a tango show. There is a botanical garden, soccer stadium, and polo games to see. almost 7 years ago
