It is a quite nice place for short stay if you like onsen. Even without a car, the bus stop is near to the entrance. Rooms are big enough and with traditional renovation, plus casement window which gives nice view. The bathroom, however, is just fine in terms of sanitary, while everyone won't use them but the hot bath or onsen. Something to note about the location, sulphur smell is inevitable in Kirishima since volcano and onsen exist. Make sure your travel companions are okay with that.
