Unsure where exactly to ask this, any guidance appreciated...

My family is flying ATL-JNB in December 2024, using GUCs to go from PS to D1. I understand the A350 will switch to the 35H configuration by the time we fly, I am intrigued by the smaller D1 cabin with only 2 rows (rows 10 and 11 per Aerolopa) at the back of D1. Questions: have there been any reviews about the experience in this smaller cabin? Any pictures available? Is the small space noisier than the larger D1 area, is there a wall between the smaller D1 cabin and PS, etc.?

In other words, I'm looking for some thoughts from someone who has experienced this smaller cabin.

I believe the 35H was due to come on-line 6/1/24 but maybe it hasn't yet and that is why I cannot find much about the experience. I did note that the A350 being used today, tomorrow and the next day are all non-35H configurations.

TIA for any thoughts or advice.
