First time in a D1 suite...
It's pretty good and spacious but the door is a gimmick.
The most comfortable D1 seat out of 752, 763, 764, 333, 359, is the 752. It's not as private and definitely less personal space overall, but it's the best sleeping seat. I don't know why the rest don't have adjustable armrests, like the 752 , to gain a few extra inches while sleeping) reclining.
