In the house before the last one, we slept in the smaller back bedroom because it had a nice view. When we had kids, they slept in the front one but we moved when they were small. Next house had room with en-suit at front, so that was ours, kids had two back rooms. Now we sleep in one of the front bedrooms and the kids share the other, the master bedroom with en-suit is at the back, but we keep that as a guest room and the kids use the other as a lego store!
I guess we just sleep where we feel more comfortable - the back bedrooms get too warm in the summer.
