Summer girls trip! Where can I stay in Echigo Yuzawa Onsen and a great view?

I'm planning a trip to Echigo Yuzawa Onsen with a friend during summer vacation. I want to take a bath in an open-air bath with a nice view or surrounded by nature, so are there any recommended lodgings? It would be even better if they had services for girls' trips and delicious meals! I'm thinking of spending around 15,000 yen per person.
