@John757 , are you still in the US? which country are you traveling to? Most other countries one can expect the host to speak or understand some English. Still, I would double check and make sure you didn't misunderstand the listing and that indeed the host didn't say anything about this strange check in arrangement.
I would make it very clear to the host that check in has to happen at the place you booked, not picking up the key somewhere else. If this cannot get straightened out to your satisfaction before you leave, call Airbnb immediately and request they book you somewhere else.
Or, if you like complete control over where you stay (i would!), go ahead and cancel that particular stay and book another one. As far as I know, guests now can cancel 3x per year and also get their service fees refunded. But to be on the safe side, call Airbnb first to verify that ,have them cancel your stay , then book somewhere else. Good luck!
