We are very keen to travel to France in 2015. We would like to spend an adequate time in Paris to see experience and see all the sights and then would be keen to base ourselves in 3 or 4 other central places throughout the countryside. Can anyone please suggest some good bases for our adventure. Should we rent a car or use trains? I am also wondering if it would be worth flying into France and out of Rome? With thanks for any help you can offer.
