Yes, listings (ads) will display at top the company information, if they are created by a business account. In do not know about Norwegian rules, but i assume you need a VAT number when running a business (And charge VAT). This number will be verified by Airbnb, but also a " Chamber of commerce" registration.
But i understand you managed to remove company details.
BTW "Professional tools" can be used by anybody, private or business.But you have most advantage of it when owing multiple listings.
