1 Christopher Hamilton-Emery #Help How do I change the category of my property Can anyone please tell me how I change the category of my property from Hotel to Hostel? 10 M Adamopoulou Hi Christopher and welcome to the Partner Community. As far as I know you have to contact directly booking.com. I had similar problem...I called my local BDC office and they changed it on the spot. Wish you well. 11 BrookAve Message or Call BdC PartnerSupport In the extranet, go to the ‘Inbox’ tab. Select ‘Booking.com messages’. Right Pane - Click on ‘See Contact Options’.
