Travelling down through France once and looking for a place to sleep I saw a Formula 1, stopped to have a look but it looked really scummy. No person working there, you put your credit card in a slot and it dispensed a key. It really did look awful.
Over the road was a Novotel, also part of the Accor group. A bit more expensive but was lovely with a bar etc which was very welcome. I think IBIS is a good mid level between the two.
