Montreal couple Justine Smith and Francisco Peres regularly rent out rooms in their apartment on Airbnb, but were hoping to have the place to themselves on their wedding night. They forgot to turn off the instant booking feature, though, and one of the rooms was snagged by another couple. Smith hoped they'd agree to cancel, but the renters pleaded with her to let them stay, since it was New Year's Eve and they'd have almost no chance of finding another place. She hesitantly agreed because they promised to be "super chill," and after all, what's the worst that could happen?
