@Dee977 Your president is obviously misinformed as to the fact that Airbnb is not synonymous with "shared-home". I'm not from S.A., so couldn't say who you should contact for a definitive answer, but it seems there's no reason why you shouldn't be able to rent an entire space, especially since your places are so remote and not near anything or anyone else.
If it were me, I'd just go ahead and accept reservations- it doesn't seem that there are nosy, nasty neighbors around to report you for it, and even if there were, you aren't renting shared accommodation.
