Reviews summaryRelaxing experience. You should try this when you are in Bangkok. Facilities are well kept and maintained. I love the modern-tradtional vibe of the place. Get some of the complimentary pandan juice and coconut rolls. they are just as good.
been to so many massages in bkk and honestly i will just the therapist i had was the worse one, she just touches my skin even after asking her to put more pressure, but thankfully the onsen was good and not too crowded on a friday evening, i prefer the other branch where the place is bigger and therapist is better
The location on the fifth floor of the hotel is really convenient, and the environment is quite spacious, offering a comfortable feel. The masseurs are just average, but overall, it's a good value for money.
Very good welcome, clean, pleasant, relaxing, and luxurious. I loved this first experience. Please note that swimsuits are not allowed. But once you're in the baths, you feel soothed and relaxed, all the stress just melts away. It's a place I highly recommend. The staff is very attentive and experienced. I will definitely come back.
Upon entering, the subtle aroma immediately creates a relaxing atmosphere. The masseuse's technique was incredibly refined, especially when addressing my sore neck and shoulders. The pressure was just right, not overly painful, but rather a satisfying sensation of tension melting away. I even drifted off to sleep at one point during the session. Afterward, I was offered warm tea and snacks. My stiff muscles felt completely kneaded out, and I'm sure I'll sleep wonderfully tonight. I highly recommend this to anyone experiencing work-related stress who needs to treat themselves!
The environment is beautiful, transportation is convenient, the staff are very friendly, and the technicians provide excellent service with skillful techniques.

Located within the hotel, with a free tuk-tuk shuttle to Thonglor BTS. The environment is good, and the masseuses' technique is not bad.
