I'm not sure now if you actually also rent to groups of guests who don't know each other, like for ex. I book for 2, and somebody from the other side of the world books the other room, and we (strangers to each other) share the bathroom??
If you only want families or groups coming together to book, then making separate listings is not the way to go.
I saw on your listing that it was booked a few days ago.
This means that u are renting to them both rooms with bathroom. All this for your base price (30eu as it is shown to me) plus the extra amount per person after 2 guests.
