My wife and I stayed for one night, en route from Italy to the ferry at Calais.
The hotel is easy to find, it's very new and is situated about a mile from Verdun city centre. The car park was huge and, theoretically, protected by an electic gate. (In practice the gate was left open all night.)
If you wished you could buy breakfast and, at other times of the day there are self service snacks / drinks machines.
The hotel room was very clean and of a decent size. It had an en-suite shower room and a comfortable bed.
All in all, the B&B Hotel was ideal for our over-night requirements.
