Our balcony cabin, 7408,was located towards the back on deck 7 (Empress) and was extremely comfortable and absolutely silent. There was no vibration other than when the thrusters were being used to pull into and out of port. The size of the shower was sufficient with plenty of hot water. The only thing I would have liked in the bathroom was a constantly powered power outlet for a nightlight which I brought. The outlet is powered only when the bathroom lights are on. This also hampers people using the plug to charge electronic devices.The bed was made up as a queen and super comfy with plenty of room under it to store suitcases.There was an abundance of closet space but no drawers in the nightstands.The fridge was large enough for us to store cans of soda and water we brought on-board. Ask the steward to clear out and store the liquor and soft drinks that are there when you arrive in the cabin.The only noise that came through was during PA announcements and loud people transitioning through the hall.The location of this cabin was absolutely ideal for reaching the Lido, which was 2 decks above, as well as the dining room, three decks below. The staircase and elevators were a few steps away.
