The main motorway that will drive you to Empurdà area is AP 7. AP 7 starts at Spain - France border and goes until Valencia. The Empurdà junction that you would have to take is number 5. From there you would take GI 623 that would drive you to Viladamat.

Once you have seen the pictures and we arrange the booking I will give you further indications. But I would like to point out that from the Spanish - French borden until the property it takes around 30 minutes.
