Ship was beautiful, and beautifully maintained. It was spotless, and we saw crew constantly cleaning and picking up.
Our cabin was great--not spacious, but well laid-out, with enough storage. The only issue was that our suitcase was a little too big to fit under the bed, but it and all our hanging clothing fit fine in the closet. The overbed storage was very handy (a little high for me; I only stand 5'2", but DH could reach fine). The bathroom was fine, with storage. The showerhead for the AQ cabin was spectacular; terrific water pressure and good temperature regulation. Mariano and Vasily, our cabin attendants, did a spectacular job of keeping us clean and tidy. They were always smiling, helpful, and appeared happy to see us. Of course, we were trying very hard to NOT be the guests whose pictures appear in front of the dartboards in the crew quarters... :)
Blu restaurant was excellent. Bogdan, the maitre'd, was welcoming and helpful. The waiters were friendly and quick. The assistant waiters (especially Vasilica and Joewhee) were funny, kind, and just all-around wonderful folks to meet! Food was good, and selection was nice, but not overwhelming. We enjoyed being able to eat there.
Cabin well laid-out and spotlessly clean. Our neighbors were noisy on their balcony, which made it rather noisy on ours, but that was not Celebrity's fault. Bathroom, while small, had plenty of storage. Hallway noise did come through occasionally, but not worth worrying about--we were so far aft that there was not much traffic.
