There are no external windows in this bedroom – it does however have another window that opens towards a loft area inside the apartment.
It seems unusual that a bedroom would have been built in proximity to a common area, and especially without a window to the outside.
Was the original building plan that way or has the owner changed the layout?
Exhaust should not exit to a common area, and even worse, would not like to be sleeping or changing in a bedroom that has louvre windows to a common area.
