definitely the best hotspring i've been too. the service is also great. all their staff are accomodating. and the food is just great! i never usually like hotel buffet but this one is different. i enjoyed their buffet, plenty of choices.
same with their hotspring pool, a lot of varieties which everyone can enjoy. kids, adults and even the elder ones. although there were alot of guests when we went there last month, the hotel and hotspring were all well maintained. very clean.
will definitely go back here with the entire family.
