Something similar happened to me! Pretty much after booking and waiting for the checking instruction, the guy asked me to go 1 mile away to pick up some keys in a unknown location, that was not specified in advanced... I wanted to cancel the reservation to pick up a more safe place... Airbnb only return 50%... this was in matter of minutes! The guy wanted 50% for a reservation done 30 minutes before sending me those ridiculous instructions... I contacted Airbnb, scaled the situation, and at the end they said nothing could be done... yep, they are enabling Scammers... Never used Airbnb again...
