We did a back-to-back out of Rome, visiting mainly Greece and Turkey.
Although we are experienced cruisers, and are at Elite status on Celebrity, it was our first time in a Sky Suite. We really liked the spaciousness and layout of the cabin, but the location was not great.
For one thing, it was right near the opening that leads to the elevators and stairway. We could hear the "ding" of the elevators.
Avoid this cabin unless you don't mind hearing a lot of noise. The cabin itself is terrific, especially because the balcony is in the stretch-out area of the ship and is slightly larger than most balconies. But the trade-off is that you'll hear all the music from the lobby, as well as the commotion at the elevators from this stateroom. Other than that, it's great.
