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…

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.

A newly opened spa on Thonglor Soi 13 offers an elevated relaxation experience with private onsens, Vietnamese spa rituals, and dedicated neck–shoulder massages… The therapists are exceptional—strong, precise hands with truly professional technique.
