Bayeux is the perfect spot from where you can visit the D-Day sites and of course it is in itself worth a visit. It has everything you might need as a tourist, campings, numerous hotels, good restaurants and a few really nice sites. Don't forget to visit the Tapestery, even though it is a bit expensive (I paid 7,80 euro) it is well worth a visit.
It also has a really good tourist information centre in the middle of the old town where they can provide any kind of information and help arrange visits to the landing sites, very handy if you don't have you're own transport.
