If possible, place your bed facing the door with a window on one side of the bed or the other. This means you won’t get hit in the morning with intense sunlight. This placement improves air circulation, too.
Unless you like it hot, give your bed leeway between it and the heater outlet. Putting the bed on an interior wall feels secure and protected. Depending on the height of the bed, you may be able to put the headboard in front of the window where the light streams over you instead of on you.
