Kittitat Kiattanavith★5

There are several pond, steam room, and sauna. With all amenities need for bathing. Staff was very nice and helpful. It's Japanese style onsen.

Good location and service

I went to the hot springs, but the floor was slimy with black mold. There were staff members spitting water, but didn't they notice the mold? What's going on? I told the madam-like staff member at the reception about the black mold, but there was no improvement. I hope the owner and management see this review and make improvements. The black mold on the floor is truly unsanitary. Especially in the washing area.
