@Genevieve71 - the price you see on the Airbnb website, assuming that you are looking at the US site and not another, will be the price they charge you which includes any conversion fees. Assuming the cost is being shown to you in US dollars. The fees your credit card charge for that conversion are above and beyond. Airbnb has no control over those. So if you credit card charges fees and Airbnb rounds up the costs to include the conversion fees, then yes, you will be charged twice. You can call your credit card company to be sure, and even know what the total bill will be.
