4195 had plenty of space, as big as and more usefully laid out than the midships Q4 we had previously. The sofa was a little rubbed up, but otherwise condition was excellent.
There was noticable vibration from the azipods below, not a problem for us but some people would be unhappy. At the worst, glassware on the shelves was jangling when maneuvering in harbour.
We also had a very prominent heavy knocking noise one night from near the bathroom in heavy seas but don't know if it was cured because the weather was not poor enough later to prompt it again.
As an aft-facing cabin there was some pitching when seas were rough which might trouble those who suffer with mal-de mer.
Cleanliness and service were excellent. The butler was pleasant and almost psychic in how well he anticipated what we needed.
