GA in Buenos Aires?

hi - this is an extremely specific question but maybe some has
knowledge?

i'm leaving for Buenos Aires next week for a two week stay, and would
love to see the city and area by air, gain some knowledge of procedures
overseas, and maybe confuse myself with some opposite compass
corrections.

does anyone know of any GA FBOs or facilities at Jorge Newberry (AEP)?
that's the domestic airport close to the city. i wouldn't think Ezezia
has GA (the large int'l airport), but maybe i'm wrong

Thanks in advance!
