I think this notion of offering a room to a refugee is an admirable show of compassion, but it does seem to be rather more about the hosts than the recipients.
In my view, this is tantamount to regarding refugees as being like students - they can come and live in your house for ten weeks at a time, and help with the washing up, maybe walk the dog, that sort of thing.
Of course, the reality would be utterly different!
How do you share a home with someone who eats differently dresses differently, has no experience of running water / western toilets / television / electric light, living in a town, and as something of a fundamental, speaks no English!
It's like people who say they are 'saving the planet' by doing without one of their two cars for a year - it makes them feel great, in reality, it does nothing useful whatsoever.
