I think we’re both over complicating this 
All you would need is to create 1 invoice (say at the end of the month, or if you prefer, you can create one for each payment). The invoice would be for the client ‘AirBnB’.
Then, simply tag the payment into your bank account as a payment from a customer, and tag it to the new invoice.
I would also suggest attaching the statement to the invoice as a record, should any queries be raised.
And that’s it! No need to import any statements or invoices
