Sorry to hear of these issues, I wish you would have mentioned to me about the bugs, I would have checked on that and tried to help. I still haven't seen any bugs in that room and didn't before your stay either. I've had many guests in that room, I have someone in there now who is long term, and no one has ever said anything about bugs. Or odors. I'm wondering if it had anything to do with all the trash in the room during your stay and that you left behind, much of it food containers. I can imagine might attract bugs and create odors.
As for the noise, I don't recall any noise in the morning except for normal moving around and trimming bushes outside on one day, which I did after 10:00AM. While I never assumed your schedule, I don't think it presumptuous to do normal work after that hour. I wasn't aware of your wanting to sleep past noon and probably would have changed my schedule had you mentioned it to me, I'm easy like that, and I want my guests to be happy.
All the best to you.
