First they offer Shuttle pick up/drop off at near by Train station, so if you have 2-3 large luggage like me, it's very convenience to travel by train (note the local train is very slow ~ half an hour ride for 5 stations)
The hotel is great, classy, high-end, with very authentic Japanese decor. The hotel gives you feeling that only you are living here as there is no common space other than the front lobby.
Both dinner and breakfast are pretty nice, multiple course and can make you full. (although there are few dishes that I didn't like, but overall it's good)
The onsen in your room is pretty nice, you can adjust water temperature as you like.
