This was a very nice experience for me and my family. The hotel itself is very nice, but the best part is the service provided by the staff. Extremely courteous and they provided for all our requests. It's in a very nice location with 9 onsens (hot spings) within walking distance. As long as you stay in a hotel in town, you get a free key to access all of them. The hotel provides you with a Onsen outfit that we found very fun to walk around in (like a kimono with jacket and wooden sandels)....
