My family had a one-night stay in Hakone on our way from Tokyo to Kyoto, and were interesed in a hot springs and ryokan experience. We opted to stay at Ajisai Onsen Ryokan since it offered that experience while also being near places that we wanted to sightsee in the area. During our stay, our room was incredibly spacious and comfortable, and the hot springs were straightforward to reserve and so relaxing to enjoy for our group. The food was pretty decent and very filling for dinner and breakfast, especially since we knew that dining options were scarce in the evenings where things shut down early in Hakone. The staff were also friendly and helped us with questions that we had. Overall, there seems to be quite a bit of good ryokans in Hakone, and I would recommend this one as one of those options.
