Accommodation is one of the biggest expenses when we travel, but what if you could travel almost anywhere in the world and stay for free? Our guest on this episode of ExtraVirgin Food and Travel tells us how. Fiona Ryan has done more than a dozen exchanges, temporarily swapping her home in Brisbane, Australia for one in cities such as Helsinki or Barcelona.   Fiona, who's a volunteer regional coordinator with the world's oldest home exchange program, the not-for-profit "Intervac," chats with host Natascha Mirosch about how it's done; the multiple benefits of changing homes with someone and gives us her tips, gained from fifteen years’ experience.    So if you've got itchy feet, but not necessarily the budget for that holiday you’re dreaming of, this episode is for you.
