My flight in 1K was a day flight, and when sitting up disturbance from the curtains to the front loo were certainly noticeable, less so when reclined. My next flight in this seat is a night flight, and I’ll report my further opinion back after that.
I would prefer that there was a third window; given that the suite feels noticeably smaller an extra window at the front would give a feeling of more space.
None of these issues are major to me, it’s an interesting exercise to find fault in a product that I really enjoyed.
