Its an iffy idea. Due to risk factors. When travelling you are pretty vulnerable with passport and everything on hand. Prime opportunity for a random "share" to rob you blind of your identity. The cite is a scam. At source they are scamming people for ID, double, triple billing them, accessing their banking info. That said I can't understand how some of these things work at all. I would never rent out my house to uberB&B or whatever its called. Even my house insurer has mentioned some nightmares about this and an industry that advises against it. Absolutely you are not insured for damage or loss of items if you book your place out. Yet people do these things all the time. To me its not worth the small amount of money you make or save. The risks are too great.
