I was brought up in the area and it is interesting to see the b&Bs now available , prices will be high as it is a tourist area. The reviews for most seem to be mixed

You will have to decide which is most important , some of these places are next to the river , most of the "hotels " are just pubs , the interesting one with an incredible view is the Hunting Tower, on the hill above Chatsworth House , maybe a little over the top on price for a fishing trip ! Whichever you choose , |I am sure you will have a great time .
