The hotel looks like it has recently been renovated. Everything was lovely and clean. The room was fantastically comfortable, we even had a sofa to sit and watch the view over the lake which was lovely. Good amenities in the room with hairdryer and tea/coffee making facilities and a fridge for putting our cold drinks in.
Due to personal reasons we didn't partake of the outside onsen that is on site. I did check and they were fine with tattooed tourists using the onsen.
Staff were extremely helpful and most, that we spoke with, speak very good English, which was very helpful for us. I would definitely recommend a stay here, in this peaceful location (we were there mid May). Get a lake view room if you can.
