Have not stayed there yet but a friend swears by it and has been there a few times now but the Auberge St Antoine is right below the Chateau and in the heart of the matter in lower town.

Send a PM to "nordsfan" or "nords fan" as he lives in Quebec and knows everyplace in town very very well.......he's on a biz trip in France right now but will be back on Thursday if you can wait that long.He'll be glad to help and will buy you a beer if he's in ton when you are there. I don't think he'll recommend the Chateau.
