We were on Aurora last month. It looked like a lot of the carpets in the public areas were new, as was the sink in our bathroom, or at least it appeared to be. The silicone around it was, anyway!
Lots of the chairs are in need of replacement. Comfortable enough, but worn. Carpet in our cabin had a couple of large stains. TV was a flatscreen, but operated like an old analogue, no built in guide, hit and miss picture quality. Some corridor carpets worn, and some window frames needed a lick of paint.
Lots of new sun loungers.
Immaculately clean in all areas though, excellent staff, and the best mdr food we've had with P&O.
