Row 6 is just fine. The seats have solid armrests between them because that is where the fold
out tables are stored. There is not a true bulkhead just either a small curtain or hard divider up above the headrests in front of you. It also has a little more leg room than the rest of premium. The only downside is there are only two power ports on the row because there are only two seats in front of you. It has as much underseat storage as anywhere else. I have sat in 6 many, many times by choice.
