We were in 12922 with adult daughter on a TA. We only had one bathroom entrance but I do see video of room you mention appears to have two doors but only one sink, not a biggie. Privacy never an issue.
Guess it kind of depends who has sofa. I'd say probably one of the best ship sofa beds I've seen but it was also new.
It is a nice room, kind of basic, one of the smallest OS we've had. We had lousy weather so spent quite a bit of time in room. Note the room, and as others have mentioned in other threads of other rooms, has a creaking issue even in calm seas. Can't recall if the OS you mentioned were ever mentioned.
Typically the prices are very close. OS gets unlimited in room water, soda, and three bottles. Maybe not a big deal if you have FAS but still nice. For us, nice to have Coke Zeros stocked and DD big water drinker. Not really helping much.
