I looked at the room listing and to be frank would have fallen into the same trap as for ex. a guest complaining about the nightly noise due to Ramadan.
You'd be better off to describe better that the room is off the kitchen and living room - even make annotations to the pictures.
When you know that you will be using the kitchen late with different people (while others will be in bed), you should communicate this immediately pre-booking to somebody wanting the room in that period.
I myself am even going slightly sleep deprived while the local Moroccan boys who have started to hang out on the square in front of my house (and bed room on that side) from midnight to 2am loudly talking and laughing now during Ramadan. Especially also since they always hang out in a crowd of around 10. Very annoying and can't wait till it's over 😕
So the more you describe the situation and even point the less positive things out to guest pre-booking, the less complaints you'll get. Maybe less bookings as before, but at least probably not as many bad reviews.
If guests feel 'intimidated' by always having to pass right through the middle of the common area to get to their room, maybe there's a way to put up a screen at least for the kitchen area to make guests feel less as if they had to pass through your activities to get to their area.
Regarding the sound. For my loft-like and quite open apartment I recently purchased a white noise machine to buffer sounds I make as well as those from the guest area above. They are adjustable, won't block everything, just muffles sound.
