We had a few units in my building in Recoleta doing Airbnbs and I am so glad they are done now. With tourism down and also long term rentals in demand again both units in my building converted back to long term rentals and I am happy. 90% of the renters were very nice but we occasionally had people that were loud and had parties.
You can't do anything at all unless there is some video camera in the lobby so maybe if so you can do something but most buildings don't have video cameras unless they are new. You can't do anything if there is no video camera. He will just deny it.
Where did the package come from
@LyellLanatone? If it was Mercado Libre you should have some protection and file a claim with them.
