This was our second Celebrity cruise and I have been impressed both times by the following features:
excellent service from cabin steward
very good quality food in buffet and dining room
Very good. Plenty of room. Adequate storage and useful cupboards above the bed. The huge mattress was very comfortable, as were the pillows. The balcony was a fair size with a small table and two chairs. Other furnishings include flat screen tv which has limited channels but you can check your account and access a number of on-board features, safe, a few drawers, a large bed settee coffee table and a chair.
Reasonable bathroom with rounded glass door around the shower. Complimentary toiletries include, bars of soap, body/hair shampoo, conditioner and body lotion. there was always a good supply of hot water and the towels were good quality and fluffy, but not super large. My one disappointment was that there was no clothesline!
