Rintaro's place is wonderful and very clean. It is a lovely space and we were lucky enough to be able to use the onsen on the rooftop twice--such a nice treat in the morning or after a long day walking around the city. His directions were also fantastic--as first-timers in Japan, they were super helpful, navigating our way from the ariport to the airbnb. The shower pressure and heat is also fantastic. Rintaro also helped us out in a bind, when we realized we hadn't printed our e-voucher bullet train tickets. We happened to meet Rintaro in-person twice, who was very welcoming. The stairs are steep, but do not hesitate to book this place! I hope we will be able to stay here again the future :)
