It was very easy to get to buy metro and is in a beautiful, serene area. Entry was free, and the staff/volunteers were helpful. There are no shoes allowed inside, but they offer slippers that are sanitized after each use.
The art exhibits and interactive displays are well thought out. Historical information is posted throughout the museum in English and Chinese, and we found it to be quite interesting. There's a nice balcony upstairs and a large sitting area with tatami mats, which was relaxing. You can see the pools on the ground level, but no swimming.
I definitely think it's worth visiting, plus there is plenty of other stuff to see in the area. And even though swimming was not allowed here, there are hot springs within walking distance that are open to the public, so bring a swimsuit and towel.
