Hello @Ivy23,
As has been said, it's a scam. It's a form email reported many times on this forum.
There's only one way to rent through Airbnb and that is
the host puts their listing on the site
guests see it there
they book and pay, by credit card, through the Airbnb website.
The whole process on Airbnb is driven by you, the guest. You see, you book and you pay all through Airbnb. The only way you pay Airbnb for renting is by them deducting it from the credit card that's registered with your Airbnb account.
This host is trying to portray Airbnb as a letting agency. It is not. Airbnb doesn't have agents and doesn't meet any guests.
Were you to follow their instructions you'd end up paying money to the host's personal bank account. You'd never see either the money or accommodation and you'd get no help from Airbnb as they would never have been involved, despite the host's claims to the contrary.
Steve.
