This was our first time cruising with Celebrity so we were a little unsure what to expect but we needn't have worried as all the family have had a brilliant time onboard and in the ports.
Constellation isnt the biggest ship but is well laid out and has a great atmosphere. yes, as some other reviewers have mentioned it is showing it's age in places and is looking a little tired in some areas, some of the balconies are rusty and some of the carpets in the the public lounges are showing a lot of wear. However, the maintenance team seem to work around the clock painting etc and the ship overall is very clean.
Our cabin was of a good size, the balcony was not the largest and was showing signs of wear with rusting etc but perfectly adequate. Our cabin steward Yogis did a good job of looking after us and was always on hand to help with whatever we needed. As we were not allowed to take our own kettle we requested one from Yogis and it was brought to the cabin immediately.
