I've stayed here twice. It's a great way to experience the hot springs in complete privacy. They pipe the hot spring water to a huge bath in your own room. It's set up next to the windows, so once you're in you can open the curtains and enjoy the view. The bathroom is sealed off from the rest of the room, so the room stays cool and dry.
The location is great, right next to the main little downtown of Jiaoxi. The room is comfortable and quiet with good views.
As of August 2021, they are doing some kind of renovation or something, so you have to check in at the desk *next door* to the hotel. That was confusing, but not too inconvenient.
