We stayed in that room 5 or 6 years ago. I do not recall any out of the ordinary hallway noise. We liked the location being right at the stairs and elevators and didn't find it to be a detriment. The obstruction on the balcony was minimal and provided a bit of shelter from the wind if needed. I didn't notice any vibration. That being said I don't know if the vibration issue has become more prominent in the last number of years. We sailed in 7190 (far aft) 2 years ago and the vibrations were very noticeable. I wouldn't hesitate to book that room again.
