one of our trips last year was to Normandy. we stayed in a fantastic apartment in Honfleur called Le Salamadre,(link below) there where 5 of us and there's a 6 foot remote controlled electric gate to park behind with plenty of space so bike are 1000% safe. Spotlessly clean. run by a very elegant and helpful woman and ideal location for D-Day beeches. Its a bit trumpy in the harbour but an amazing place to stay.
Its about 4 1/2 hours from Calais on the 'twisties' (personally, I'd do this) or 2 1/2 on the M-way
I would HIGHLY recommend it.......
