Some homeless people have been put up temporarily in hotels, even an airport.
Lots of stories about this:
"Coronavirus: Heathrow Airport sheltering '200 homeless people'"

https://www.bbc.co.uk/news/av/uk-52027172/coronavirus-how-the-uk-s-homeless-are-coping-during-the-pandemic"UK hotels to become homeless shelters under coronavirus plan"
https://www.theguardian.com/world/2020/mar/21/uk-hotels-homeless-shelters-coronavirusOf course some people are sleeping rough because of issues around addiction and mental health and a minority (got to stress that it is a minority) of people, as hard as this is to grasp, prefer to do so even when there are hostel beds available. I don't know what's bee n done about that minority of people in this crisis.
