Marpent, France.
I recently asked a question regarding recommend vets near Calais and got some some helpful info back from WC, esp about using Google maps to search and then seek.
In short it resulted me in finding a French vet close to the French / Belgium boarder, which is where I was at the time, the whole process only cost 6.90euros, which was basically the price for the 2 x worming tablets my 22 kg Lurcher had.
Pet passport signed and was a great service. There is parking at the surgery, large enough for most vans. Incidentally there is a great free air with all free services close by at Boussios, 50°17′17.58″N 04°02′44.16″E
Limited English spoken, but I did call first to make an appointment with no problem.
