As I mentioned before, there was an earlier burglary of another nearby apartment which is ground floor and importantly is identical in layout of rooms, window positions, door positions, and the sloping ground whch makes the 3 side windows too high above the ground to reach.
So at this other apartment, and exactly the same at 5A, the burglar cannot choose freely from the 4 windows, because 3 are ruled out by being too high above the sloping ground, he is limited in choice strictly to the one and only north window, the one which is reachable from the ground.
Just to make it clear, this is not 5G and it is not 5L, it is another one very nearby, ground floor.
IMO if that earlier burglary were investigated it seems likely to be found that entry was probably through the one and only window accessible from the ground (the exact equivalent same window as entry was IMO attempted into at 5A but inevitably disturbed before actual entry).
