@Maria12752 With your hundreds of past reviews, it looks like you've got a deep base of experience with navigating the ins and outs of renting two units in a shared house pre-Covid. But if you've let yourself be strong-armed into signing onto that Corona Cleaning Pledge with the current arrangement, don't be too surprised if you find yourself backed into a corner where guests start getting free stays. Take a close look at what Airbnb has demanded that you agree to, and ask yourself how much of this really makes sense. Realistically, continuing to list under the current requirements means that you'll be breaking the rules on a daily basis, so you'll have to be sure to screen your guests and filter out people who are likely to report you.
Sure, you can ask guests to clean up after themselves in the shared bathroom and kitchen and to wear masks every time they leave their bedrooms, but are you in the house 24/7 and able to enforce this? Can you guarantee a freshly sanitized environment in the home at all times to an unvaccinated guest who foolishly booked a room in a shared bungalow?
Any suggestion I could make to you would require that you break the current Airbnb rules in order to run your household the way you successfully did before the new protocol came into place. But I can't advise that in a public forum for the same reason that I wouldn't recommend a drug dealer or propose that you open an illegal hostel in Paris. So I would only recommend that you hold off on re-opening your listing until the current Covid protocol has either been phased out or adapted to a reality in which all people present in your household have been vaccinated.
