Older building, but comfortable stay and very friendly staff. Unfortunately all the rooms had 2 twin beds, rather than double beds, so we really had to snuggle. At least the bed was comfy. The view from our room was great, gorgeous view of the lake. The Onsen was delightful. We had breakfast included and there were a ton of options, really great spread!
If you're taking the tourist busses there is one that stops right outside on the main road, but it's a bit of a walk up a hill to the hotel entrance.
