Thanks for sharing.
It seems SV is doing efforts in improving their FA skills, as you got 2 good crews on 2 flights. I had a similar trip two years ago (MXP-CGK and 9.5 hours layover in JED) and the crew on the JED-CGK leg left me unimpressed, almost zero interaction, food service rushed, while hard product and food quality OK.
Tempted to do again a ATH-CGK with family end of this year as it has a very good J rate, hopefully by the time all flights will be already moved to the new JED terminal and new lounge.
