Our obstructed ocean view vertical cabin that was across the hall from where the stewards and other crew would enter. Sometimes you'd hear noise coming from there but not much.
Any noise basically came from noisy passengers walking down the hallway. Usually they weren't too bad but there's always some obnoxious drunk, child that hasn't been taught inside voice, or perfectly sober adult that hasn't grasped that concept as well, being closer to the stairs and elevators meant that you'd hear them more than you would in traditional horizontal facing cabins.
What you do have is the lights from deck 7, even thought the drapes were light blocking some would still seep in from the bottom so I'd suggest a sleep mask.
