We had a blast staying there, from when we arrived late afternoon until we left. The staff were amazing, super friendly and polite. The guy at the front desk even gave us some tips on where to go nearby.
The food in the restaurant is good and well-cooked, but it took ages for us to get our food that day.
We loved how easy it was to get to the hot spring pools. The big one has three sections (around 30°C, then 32°C and 39°C), and there's another pool (38°C) near the restaurant.
There's other stuff to do around there too, like 18-hole golf, mini golf for the kids, horseback riding, and a playground.
