Export airbnb calendar to iPhone and Mac Cal

Has anyone been able to do this? I feel like it should be very easy and yet here I am asking you guys.
I would ideally like to be able to have my bookings marked on my iCloud calendar with is also linked to the standard iPhone calendar, can anyone explain how to do it?

You iCloud account has to be added to your iPhone via Settings. Settings > Mail, Contacts ands Calendars. Once added it should all sync, although, even though I have iCloud and Google, I only use Google calendars for this purpose.
