We had booked the couple's private Bonsai Sauna experience—Himalayan pink salt sauna, one of a kind place... Although it looked very aesthetic with the beautiful decor and ambient lighting…
I booked the private Sakura onsen room, which includes a hot onsen bath, a cold plunge, and a steam room. The facilities felt quite new and the room was very private, making the whole experience feel calm and exclusive…
My wife and I had such a great private onsen experience here today… Genuinely great, and such a good location! Highly, highly recommend.
Great service and place is clean. The therapy person is very great.
Amazing spa in Thonglor with a great variety of treatments. Really enjoy both the steam & sauna rooms. Will definitely be coming back.
A really nice relaxing and experience for the weekend. The overall atmosphere is made for peace in body and mind. Definitely gonna come back to this place.
Nice and clean onsen. You can have a private room and relax fully. Massage is good, they have lemongrass oil—very nice smell.
I had Jaae as my masseuse, and she was absolutely wonderful… Her hands have a magic touch, and the massage was one of the best I've ever experienced.
Private onsen and spa in the middle of Thong lo. I spent 2 hrs here. The Mineral salt Japanese onsen and Ice bath are awesome. Highly recommend this place!
What a great experience. I was looking for a relaxation spa with wellness, a cold plunge, and a sauna, and this place had it all… Apple was incredibly kind and welcoming. Highly recommended!
We tried this new place as it just opened and took the 2 hour private onsen + Vietnamese Spa session. It was very refreshing and the place looks gorgeous! Highly recommend!
