Or choose your clients well hehe. I have a friend who recently sold his apartment, which he was using as a temporary rental. The big problem were the people who rented it. Seems foreigners (of all nationalities) like to come here to party, and they can be very disruptive. Stories of guests getting out of the elevator drunk on the wrong floor, beating on the door of the apartment they think is theirs when their key doesn't open the door, as if the door will magically open. Noise, carousing at all hours (of course, it's been my experience the Argentinos like noise when they generate it themselves - but it's their noise, not visitors'), etc.
The building consortium fined the owner a couple of thousand pesos each month which he fought legally and won (after two years), but it caused a lot of problems with the owners in the building. Including the neighbor across the hall, who continually reported that the guests were peeing outside the door - and the odor went along with his complaints. But the owner of the apartment in question realized that it was impossible that every guest who checked into his apartment was peeing before they could make it to the bathroom, so he put up a camera and caught the neighbor across the hall peeing on the door and the mat outside the door...
This was in Recoleta, Callao and Posadas. A really nice place.
Yeah, you could end up in some issues if you have poorly-behaved guests, which is pretty likely with short term rentals. It makes it hard to be part of the community.
