Deck 9 is the best deck on this ship. There are no public areas above or below and it is only 2 flights up to the pool deck and Windjammer.
The biggest thing that stood out in our room was how Quiet it was. We didn't hear a noise from any other room the entire trip. The second things was the comfort of the beds. Best beds I have slept on in a cruise ship. All 4 of our beds had nice memory foam toppers.
The room is a little larger than the usual interior room at about 160 Sqft. It allows for a sitting chair and small table in front of the TV. It makes it feel a little more livable and also helps when accessing luggage. The Closet is a little small still.
The bathroom is about the normal size but a nice feature is a circular shower stall with doors instead of a curtain. The vent suction was strong and the water pressure was also strong.
