I live in BA, Argentina. It's a very beautiful city, really huge. There are lots of things to see and do here in BA. It's a bit hectic, but that's cause it's big and there are lots of people. I've also been to Bariloche (Rio Negro), Tunuyan, San Rafael, Mendoza City (Mendoza) and to Colon and El palmar (Entre Rios). All of them gorgeous places, and very different from each other. I don't know waht you'd like to know but feel free to ask!
Cheers!
