Nah, I'm Australian. But as I said I'm a career international teacher so I've been in Bulgaria for the past 5 years (and Tokyo before that - variety is the spice of life!).
Most of the teachers at the school are Argentinian. I'm not sure what the deal is with fees (that students pay) but if those are hit by inflation they couldn't really have the foreign hires getting a guaranteed dollar based salary and the locals seeing theirs get devalued massively. Especially since, if it did all spiral out of control, we're the ones who would be able to get out a lot more easily than the Argentinians.
I don't know the specifics of housing. It would be a 2 bedroom, furnished, apartment. Possibly at the school itself, possibly in Quilmes (basically they fill the apartments they own and then they rent). You do get a say in where you live (if there's no spot at the school), so apparently some people live in Buenos Aires but I don't want the commute.
