Hi @Camila804
It sounds as if he claims that he is hosting the apartment on Airbnb. Ask him for the Airbnb link, study his profile, details of the listing and reviews and (if everything looks good), tell him you want to book on Airbnb. If he genuinely feels his place is excellent, he would welcome the opportunity to get a great review from you. He can still offer you a special price when you request to book on Airbnb, even if his regular rates are higher. You will both at least have Aircover and a dispute resolution process. One wonders why he did not approach it this way to begin with ... I understand why you are concerned.
