Hi Craig, if you cancelled several bookings, no reasonable person will book with you. Would you want to risk arriving at night after a long trip with no Internet service to find out your host cancelled on you? Where would you go? Call airbnb on rooming costs? Seaarch listings and yellow pages on data rooming? Pay a hotel room at thrice the original price?
Cancelling from your side on your own is a thing you should Never do. In case of emergencies, call airbnb first and they will help you or cancel on their behalf (accidents, blown up water tank, hurricane etc)
you could try now to sell via a low price, but not too low, as that would seem an even crazier deal. If you still can, leave a public answer on the cancellation remark, explaining it. It reacts like a normal review. Otherwise leave an explanation in your profile, something that explains a period of emergency situations but is safely over.
If that does ot belp , sorry: does not help, an account in your partner's name would be a good idea. (I can't edit ling texts on the phone, sorry for spelling)
