The Buddhist shrine can be placed in the southeast room of this apartment, facing east by the west wall.
If this room is occupied, the Buddha should live by himself.
If you don't want to put the niche in the bedroom, you can put the niche on the west wall of the living room near the balcony and put it eastward.
If there is a shrine at home, no matter which room you put it in, you should hang a yellow curtain on it.
