But she doesn't need to pay for food or clothes or toiletries cause she said she's going to free places. Apart from rent, pretty much she needs to pay for the internet and electricity to run said internet (often covered by rent)  I'm not sure how cold things get where she's living, but when I lived in Canada in a basement I just put on a hoodie when I got cold. I didn't even have to pay for heating, but it just seemed more sensible than turning up the heater... and if electricity is covered but heating (usually water running through a radiator) isn't covered, she could just get a space heater and plug that in.
