Even more important - buy some local Cider from the site wardens (who incidently don't speak English but manage to make themselves understood.) It is not a head-banger but it tastes wonderful.
Ablutions are spotless, there are clothes washing facilities, a sports field, and as others have said a nice albeit steepish walk into the village which has several restaurants and a large working abbey with English connections. The site was well protected from weather/winds until they cut down the 20ft high 30-40yd long beech hedge!
Nearest town is Brionne which has a medium Carrfour and a couple of smaller supermarkets plus some nice browsing shops.
Site is very quiet, not generally too busy, and as the view to the SE is clear sat reception is no problem.
Highly recommended.
