I live on a apartment on the third floor, and a little space "balcony" to make the laundry, so i put always neewspapers and Maca go to make her bussines there.
The basenjis are very clean so she walks to do and comeback inside the apartment, of course the balcony have concrete half wall, so he cant fall,
When i back home i pick up the poo and change the pappers if not, she makes poo on the next area, my kitchen.. haha.. and then i pick up again and check the newspappers. She dont use the place if are too dirty.
So just need to keep clean her "poop area" and she will use always.
I always use a lead to walk her on the streets and if she make poo i will pick up. And thats all.
If rains she makes inside. But not a big deal, just more papers to clean.
And of course her bed are not on that area, i think that she wont like to sleep or rest on her poo place.
