Yes we rent out our apartment in BA to someone local here and get paid in pesos every month. All done above board with a yearly contract agreed and signed.
As Eastbay 1K said I suspect any short term lets which may be paid in pesos will be priced to match the official exchange rate.....we're not daft down here you know.

If they aren't they're probably best avoided.
