We booked a house in Norfolk, UK for a week, and received confirmation from Airbnb. Everything seemed okay so far. The cost was obviously in pounds. We used our AMEX account, which is in the UK. We clearly paid in pounds from a UK bank account, but because our address is currently in Australia Airbnb charged us in US dollars and 8% for the currency conversion. So Amex paid out in dollars and converted it back into pounds for us to pay off the credit card in pounds. The house originally cost £681 and it has cost us £727. Unfortunately, it didn’t end there. The host cancelled, so I telephoned her to find out why; she said she hadn’t heard of us. The dates had been booked out for ages. She was so fed up with Airbnb she was withdrawing her property. So beware folks: check which currency you are paying in. My complaint was dealt with by an email quoting some obscure terms and conditions. I had the last laugh though because I was lucky and received a refund into my Amex account in US dollars, which Amex converted back into pounds. Due to a more favorable exchange rate, I actually made a very small profit. I will never use Airbnb. I think we got off easy.
