The problem, as people describe it

Airbnb hosts struggle with guests causing persistent, noxious odors (vaping, strong perfumes, cooking) that permeate their properties and even adjacent units. These odors lead to significant cleaning costs, lost booking days due to airing out, and potential health issues for hosts, costing them revenue and peace of mind.
