Is there parking?
The Moulin is in a pedestrian zone. It is better to come without a car: Strasbourg station is a quarter of an hour’s walk away.
If you come by car, you can stop to unload on the small place des Moulins, 15 m away (paid). The cheapest car park is Centre historique Petite France, rue de Molsheim: 900 m on foot, flat rate €15 for 24 h.
