We are only 15 mins from Bergerac airport, very easy journey. Also you can fly into Brive and Bordeaux which are about 90 mins away.

If you are driving from Calais about 9 hours. You may want to break up journey with a stop at Tours. (please let me know if you want advice re this)

A new fast train from Paris to Bordeaux with connections to London is another alternative. Maybe hire car from Bordeaux or train from Bordeaux to Bergerac. Detailed instructions will be sent at time of booking. Where are house is you will definately need to hire a car
