There will be no quiet and rest.
I have not seen any low cost carrier that would have a bulkhead in front of 1ABC. I recently flew 2D GDN-KRK on FR and you can hear everything from the galley (including Galley FM gossips that will definitely take place on this relatively long segment). I guess there might be no curtain between C and Y, either (as Blue Air did not need it, even LO own Maxes did dot have courtains for the first year of operation). I would expect a very premium experience
I actually dug out a few videos of past Blue Air Max flight reviews and the bulk head was definitely there - on both sides. I'm guessing a FF with LOT may be able to shed definitive light here.
