11A is right in front of the F and J lounge/sitting area, not galley per se-no food service or prep there at all. Very few people will be using lounge but 10% of the time there may be a child crying or being nursed or obnoxious selfish pax speaking loudly and laughing-usually while drinking. There is also a self serve bar on that A isle side of the lounge. Just make sure the curtains, which seperate the cabin from lounge area, are closed then snapped into place with fasteners to keep them that way so light and noise to an extent, don't disturb you(there is already an overlapping split down the middle of the curtain for access- although some pax will stop in bewilderment wondering how to get through the closed curtain . Some annoying crew will unfasten the curtains for their convenience at times but just get back up and refasten. If it keeps happening ask to see cabin manager to put a stop to it. There is definitely much more room and space in that seat with a larger footwell making sleep very comfortable. The forward smaller J cabin is usually reserved for senior tier QF FF as well as being a much more intimate cabin than what is known as the 'dormitory' rear, larger J cabin. The seat is closer to the window with dividing wall between you and isle as well as having a convenient storage draw in the bulkhead, Enjoy.
