10 / 10Outstanding·Jul 2026
The hotel was impeccably maintained and a very luxurious reflection of a typical Thai design.
Service was outstanding and hospitality and personal service as good as it gets.
Rooms in deluxe condition and dining options were good although the dining options seemed to be in changes to higher quality than some.
The Sunday Brunch is renowned for high end also drawing a very high end Thai and foreign clientele.

I have been coming to Bangkok for over 30 years and have stayed in many 5 star hotels. Anantara is the BEST---not just because of its location and facilities and food but thier staff is incredible---ever helpful and always smiling. I can't wait to return.
