I chose Nui spa because I could spend time in a private area. I stayed for 3 and a half hours and enjoyed it thoroughly.
The process was smooth as I only had to show the Klook reservation QR code at the reception, with no complicated procedures!
The mud bath and herbal bath were available in a completely private space, and I could use them for longer than the allotted time, which was great.
Please note that the showers and powder rooms are basic.
The changing area was also shared by men and women, and it was a simple setup, like a fitting room in a clothing store.
There was a simple Panasonic hairdryer, and even though I have long hair down to my back, it had enough power and I had no problems using it!
I also received a free Grab discount voucher, which saved me money on one-way transportation.
Overall, considering the price and other factors, my satisfaction was high, and it's a place I would recommend to others!
