@Barbara2680 Find a place to 'stay' and then apply your voucher at checkout. To avoid the inevitable scam artists I would say you should choose a host with reviews prior to March. We also went for a home share host as it is less likely that these people are as rich as some of the bigger listing companies.
It is a horrible situation and the replies you will get from your host will probably be uplifting. Do share it here to inspire others to follow your lead.
