We chose this cruise after having been on the 2016 version which wasn't a full circumnavigation. This one was and it's cold in the UK in January.
Some comments follow:
1. Embarkation/disembarkation was very good. (We'd reached the top Peninsular Club tiers so it wouldn't be so good if you are below the Caribbean tier).
Essentially the cabin was a good size and just about adequate for what we needed.
Our sofa did have drawers which we definitely needed to store some of the many things we seem to carry with us.I don't think that many of the cabins had this type of sofa.
There were some minor stains on the carpet and some 'trial' bits of fluff we left on the carpet were still there after our cabin had been cleaned. This wasn't much of a surprise given the number of cabins the steward has to clean.
Overall, I'd say the cabin was OK. Not luxurious, just OK.
