CDG to Auvers Sur Oise by taxi and places to stay there

I'm flying into CDG and my daughter is flying into BVP (Beauvais) in April and we're looking for a place to stay on our way to Giverny and then Brittany. It looks like Auvers sur Oise would be a nice meeting place for us for the first nite, but I'm not finding many places to stay there. So first, is it accessible by taxi from CDG and Beauvais? How much would it cost? Around 80 euro? And is it a good place to stay-can you recommend any places? 2 beds, non smoking, B& B or hotel...Other suggestions for towns to stay close by are welcome...I'm just trying to minimize taxi cost; I'm not up for much after a long flight. Will do trains to Brittany. Thanks, Clare
