Miscellaneous: If you plan to rent a car to visit the area sourrounding Paris, do not forget to bring a very good route map. Signals in this area are not so good (I compare them to the ones you find in Italy) and it is easily to get lost. Then, you are never given information about how far is the destination you are about to reach.
I give you the link of our french yellow pages ( in english ) , where you can find pictures of streets, map of the place where you want to go and of course the adress :
Don't forget good maps of Paris.
If you forget them don't worry: there are tenths various maps sold in many points in Paris.
