I have to say Argentina has an enormous variety of landscapes. I don't know how much time you have and which are your preferences. You can't miss Buenos Aires, it is a special city day and night. Mendoza is another province to visit, the south of Argentina (e.g. San Martin de los Andes), the north (e.g. Jujuy, specifically Tilcara).

Palermo is great. There are a lot of things to do there..Spend one evening there at least.
