We had cabin 8100, a JS facing the back of the ship.
The cabin and balcony size were outstanding BUT this is an older ship and it simply cannot handle speeds in excess of 15 knots even with calm seas without without causing severe shakes and rattles and where in the back of the ship, but worse in the cabins itself.
The first night out at sea at over 20 knots with a calm ocean you simply could not sleep in the cabin, the rattle and shaking was like a 7.0 on the Richter scale. Worse, it would be calm and quiet for about 5 seconds and then the shaking would start for about 10 seconds and it did this all the time!
As mentioned above, cabin 8100 is a rear facing suite with a balcony as large as the room.
It is however in the back of the ship making it impossible to sleep at night any time the ship speeds up above 15 knots as it shakes back there like an earthquake.
