Stopped there last September for a few minutes to dump grey water - not overnight. Seemed a decent aire and not too far from the town centre. It is near a ring road so might be a bit noisy.
Below is an image from the map on CC_Infos.
And a comment from the most recent Camping Cariste poster on that aire. 13/11/2014 l'eau fonctionne - aire un peu bruyante mais super bien située par rapport au centre ville - carfour market au bout de la rue

We have stayed there twice on single overnight stops......... plain and simple.....not too noisy......convenient for the town. Not somewhere you would want to spend too much time around the van as it is indeed by the road.
I'd stay there again if I were passing through.....
Not the greatest of aires its best part of a mile to the tourist office if you wish to buy a token for the water. Stayed last November after visiting Linda's great uncles grave on the Somme. Didn't notice any particular noise but even in November it was packed with twice the number of vans as official spaces.
Nothing wrong with it for one night, as, has been said it is a good walk to the centre but not too far, and the aire is on a bit of a slope and against a car park , but arras is well worth the visit, and as I said nowt wrong for one night.
We didn't use the aire but spent the day and evening in the town in early September when they have a big fireworks display in the main square. We thought it was worth the detour - the citadel/fort and the cathedral were interesting, and the Carriere Wellington WW1 tunnel museum is just down the road.
