I want to rent entire flat/apartment as a whole (self-contained apartment), not separate / single rooms (booking greenhorn)


Im puzzled. I have apartment/ flat, the apartment consists of bedroom with tv, big bathroom, big living room with kitchenette and terrace.

Now My problem is every time try to add my flat to booking com I ended up with my apartment cut in the slices.
You can book bedroom or living room separately for 4 people.
I just wont to rent My entire self-contained apartment / flat for 4 guests. Not the parts of it.

Im trying to figure out this by my self for basically 36 without sleep Im exhausted, please help.

Oh when im login in to extranet  my login link starts with https :// admin.booking. com/hotel/hoteladmin/ wtf I do not have nor own a hotel. Im clearly doing something miserably wrong.
