There were four adults in our party, staying in adjoining balcony staterooms (7192, 7194), in Concierge class. We all have cruised before on several other cruise lines, and so are familiar with the environment.
Overall: The onboard experience was a disappointment. There were too many issues that arose that should not have arisen, and when they did they were either ignored or not handled well by the ships' staff. We did not feel respected as passengers, getting the ongoing impression that our presence was an inconvenience. We would not travel with Celebrity again.
Accommodation: cabins were clean and well-appointed. Their location near the stern was ideal, and we were not disturbed by external activities or engine noises. We would book such rooms again. Our room steward was helpful, but his command of English was limited to a few stock phrases. It is worthy of note that our balconies overlooked those on the deck below, resulting in less privacy for those occupants who had paid more than us for their deluxe suites. Plus, the unusual idea of having 'portholes' in the floor of the Oceanview Cafe on deck 10 was disconcerting, too, as they allowed viewing of various balconies.
