are Airbnb's easy targets for a break-in?

[Josh Dillingham]

a family member of mine has an Airbnb property. they had their house cleaner come in after their last guest had left. a few days later, before the next guest came in the cleaner returned to the house because he thought he had left something behind. when he went inside he found that someone had been staying there. the bed had been used, there was beer in the fridge, dog hair on the couch. this got me thinking about how easy it is for someone to log on to Airbnb and look at a particular property to see if there is availability that day, then you could just walk up to the house, knowing it is vacant and try all the windows and doors to see if the last guest left anything unlocked. this seems like a pretty clever idea for a vagrant looking for a place to crash. has anybody ever had this happen to them? I'm thinking these people got in through I bathroom window that the last guests had left unlocked and the cleaner hadn't noticed. .
