TL; DR version: On a grand scale the room really nice, and actually quite spacious, but some of the little details could stand to be ironed out.
This cabin is beautifully appointed with wood (or at least wood-like floors). My wife and I had ample space to store all of our clothes, and our quite large suitcases fit beautifully beneath the bed. However, the drawers and cabinets all operate on a "push-in" rather than "pull-open" basis, and this push-in system was finicky on both the closing and opening side; it was often hard to get a cabinet door to open or stay closed as desired.
The in-suite hot-tub is beautiful and fun, but small even for someone like me, who isn't very tall; it's hard to spread out comfortably in it.
Another reviewer noted that hot and cold were reversed on the faucets; this was *not* the case in the cabin we were in, so it must have been a feature or bug unique to his cabin.
The balcony is a lot wider than on the regular balcony rooms, which is a nice upgrade, and the room does come with a "cell phone" that works anywhere on the ship as well as the lavazza coffeemakers, which were very nifty. You do get a large-screen TV.
Bathrooms: You get dual sinks (nice, but mainly for the real estate on the shelves than the dual heads themselves). The showers come with six mini-jets, all on the same wall as the main shower head itself, but only the bottom four of those can be used at the same time as the main shower head.
