Hello @Augustin10 ,
If you plan to rent them separately—meaning two different guests with two different reservations—then you will need two separate listings. This is because if one guest books a listing, it will no longer appear as available, so you need two listings, each with its own calendar, pricing and availability.
Consider styling them slightly differently so that, when looking at the photos, it is clear that they are two different listings.
If you plan to rent both together or only one of them at a time , then you can use just one listing. I can share more details on how to set it up if needed.
