From a posting by Alissa Pemberton on the Community Action:MK website we read this:
“Sanctuary Hosting is a registered UK charity that provides temporary shelter to homeless vulnerable migrants, refugees and asylum seekers (guests), many of whom are also destitute.
They match guests to generous people (hosts) who have a spare room to accommodate them temporarily, just like air bnb but at no cost. They work in the Thames Valley area, predominantly in Oxford, Milton Keynes and Reading. They currently host 16 guests, and have made available over 7,800 nights of accommodation since they started in July 2015.
