I second Dave James reply,its a nice family run 2 star hotel in the new Oradour village and only a couple of hundred metres from the old village.Was there myself last year and am passing that way again in July on my way to the Somme.
South of Oradour-Sur-Glane just off Junction 43 of the A20 is a Bikers Bed and Breakfast which you could stay at - Cheaper than a Hotel and full English Breakfast
