Left facing outside closest to the door. But since she's always getting up at night for random stuff "i'm thirsty, it's cold in here..." and always having to climb over me since it's up against the wall i've been sleeping on the right with better results.
Right side. It was always the closest to the door till I moved last time and the fiance moved in. I just continued to sleep there and she took the left. I also have one side of the couch I sit on and so does she...weird.
