"Very nice onsen hotel and dog friendly. Japanese style room but has beds and comfortable chairs, spacious rooms with seperated shower, toilet and sink rooms. It is very clean and no smell at all (we dont have dog for the stay there). We booked the half board and the 10-course dinner and elegent breakfast were excellent. There is a city bus stop in front the hotel and it directly connects to Hamamatsu station. The onsite onsen is great. It is two bus stops from the beatiful flower park. Highly...
