I want to see the night view of Mt. Hakodate in Hokkaido and take a bath in the hot springs at Yunokawa Onsen. Please tell me the best place to stay for a solo male traveler.

I'm going to Hakodate to see the night view from Mt. Hakodate, one of the three most beautiful night views in Japan. I want to stay at Yunokawa Onsen, but can you recommend a hot spring inn for a man traveling alone? Preferably one with breakfast.
