We sailed Celebrity Summit to Bermuda after sailing on her to the S. Caribbean previously. She's not a newer ship and she's due for a face-lift, but she's clean and well maintained. We had forward cabin 6000 for me, my wife and my nephew. The cabin was great, except for the usual contortions needed in that small a bathroom.
Our stateroom attendant, Constancio, was excellent, always making sure we had everything we needed. We sent one bag of laundry out and he dropped it off in the evening and we had it back after lunch the next day. Well done by the laundry team.
We had dinner in the Cosmopolitan Restaurant every night and had absolutely no problems. After reading so many complaints about the dining room food, I wonder about some cruisers' expectations being unrealistically high. Our waiter, Diego, and his assistant, Rudy, were both excellent and our food was always the correct temperature and always presented well. Diego was very knowledgeable and his recommendations were always spot-on. We also found that the food at the buffet was fine as well as the grill (in fact the chili at the grill was outstanding...I loaded it into tacos every day). Kudos to Executive Chef Andy Bouchard for the tight kitchen that he runs and his friendly open personality. He was great to talk to and to pose for pictures with.
Cabin 6000, forward ocean view cabin on the Penthouse Deck. Nice view right out to the helipad. Not much drawer space, but decent closet and larger than the standard ocean view. Small bathroom with very small shower.
