@Brynja0 When I was new to hosting I called Airbnb about this same concern and was told it would not effect my stats or ranking negatively - Only cancellations would. I also got those notices to 'check my listing' for accuracy or something like that, and, as with you (and many hosts here), it was not my listing description that was not accurate but the person inquiring who had not accurately read my listing!
If I ever got something that seemed like a genuine warning from Airbnb, I would call them right away and protest. I have proven myself as a host (now a super host) and until if and since it is unlikely Airbnb can ensure people inquiring are actually reading the key points of a listing (like maximum occupancy) we hosts are going to have to keep fielding these types of questions.
What I did on my listing was put the max occupancy and who my cottage is best suited for in the Summary at the top of the listing. I also say there that the Cottage comes with a 'kitchenette' - not a kitchen. So that helps weed out families of 20 who want gigantic kitchens with stoves. I figure most people at least read the summary, so that may be a tactic you want to consider to help avoid this in future.
