Romantic Weekend Away in Derbyshire area UK?

I want to rekindle the romance with my man by having a romantic weekend away. I'd like it to be posh nosh, 4 to 5 star rating and a place where we can be just in our own world. If anyone has any suggestions on where we can go. The budget is not an issue. But it must be in the Derbyshire area or anywhere county close by?
