@Art-and-Nichola0 If you only want to take long-term rentals on Airbnb, you can set a minimum stay amount to 30-days with a maximum of 120 or whatever number suits you.
As for scented products - your #1 house rule should be a short list of what is not allowed that most guests will not even think about as being scented, So house rule should say the big triggers for you (example): no perfume, no scented shampoo/conditioner, no cooking curries, no scented hair spray, no scented body wash/scrub/soap/lotion, no outside cleaning products, no candles/air spray, no dryer sheets, all products in the home must be scent-free and leave no lingering odors, or whatever you need it to say to be very, very clear. Then plan to send a list of additional products that are typically scented that would be forbidden after booking confirmation (including foods, herbs and spices that will trigger a migraine). The way this is worded today, it sounds optional and does not provide any real details to the guest what is allowed or not. "Scent-free" for someone who is not sensitive to scents is not descriptive enough so it is going to be interpreted in many different ways and most won't even think about the products they use as being scented. You have a specific expectation, so you must lay it out as very specifically.
