It’s a nice place! The room we stayed in could fit me and my parents, but I think it’s definitely best suited for two people. The stairs are a little steep, though, so be careful if you need space to climb up and down. Although we didn’t use the kitchen, it had a lot of the things my mom needed if she wanted to make a simple meal.
Our host was very nice, too!! Often wished us well, especially when it was starting to rain. She was prompt and responsive, which we appreciated. We also got help figuring out the way to Nishi-Kokubunji Station when our map app was unclear.
