Finnish travel blogger Anna Koskela (she writes in Finnish, sorry) has done a pretty down-to-earth review on A330 J XIY-HEL:

You know how the glory of J travel fades with every J flight you take, and this has happened to Anna, as well. Her old J reviews were a lot more oohs and aahs. But now I think she has reached the point where her experiences and comments start to become very useful for AY, too, so let's hope they read her post.
