<human>: This February, I'll be starting my semester abroad in Buenos Aires, Argentina. However, the cheapest tickets I could get (arriving Feb. 14th) are scheduled for a week before my program starts (Feb. 20th). I have family friends who I can stay with, but I'll be largely on my own for the duration of the week. Does reddit have any suggestions about where I should go or what I should do?

Over the course of the 5 and a half months I'll be there I plan on making my way to patagonia, mendoza, and iguazu (mostly adventure/outdoorsy activities), so I mainly want to familiarize myself with the layout of the city, mass transit system, and "tourist-y" type places. I'm a total foodie and love exploring cities, with a passion for trying everything at least once. I'll have plenty of time to explore further and I'm looking for a general introduction to the city. Any help is GREATLY appreciated!
