The Internet spawned a collaborative economy. Web sites such as Airbnb allow co-owners to rent their apartments to third parties a few days a year. This accommodation formula, intended for travelers, sometimes generates substantial income. For this reason, some owners are tempted by these easy pickings. And they believe they are entitled to do so, (wrongly in many cases) and to use their private portion as they see fit.
Many co-owners are unaware that this activity is prohibited in their building. Others are fully aware, but are unconcerned. However the incessant ins and outs of strangers brings its lot of disadvantages. Late and noisy arrivals, as well as departures at dawn are generally not compatible with the lifestyle sought by the resident-co-owners of the building. This practice can potentially have a negative impact on their safety.
