The whole experience was excellent- having been used to smaller lines like Seaborne we were worried about Celebrity. The cabin was spacious enough - no bath only a shower but spotlessly clean. We paid a little extra for the Concierge Deck where we received capanes and fresh fruit daily - luxury robes and plentiful toiletries, personal stationery etc.
The cabin attendant was excellent and the cabin was spotless every day.
Breakfast was taken in the restaurant rather than the buffet and was freshly cooked and well served.
Noise from the public rooms above ( sundeck) which has stone/tiled floors and the noise from passengers in hard shoes at night was most disturbing - Cabin 9056 Celebrity Constellation
