The bedroom and the bathroom in the listing are indeed for guests only, but when filling in the details of the other areas available to guests in the 'property and rooms' section ('rooms and spaces' sub-section), I have clearly indicated that the lounge, kitchen and garden are also available to guests on a shared basis with me. I can't see that information reflected in that format in the final listing, so not sure of what's the point of that section.
That information about shared spaces is repeated in the 'listing description' (guest access sub-section'), and the 'amenities' section, both of which guests can find if they take the time to read the whole listing.
Still, thanks for taking the time trying to find a solution! 🙂
