Reviews for Anantara Siam Bangkok Hotel
The hotel felt more like a smelly and noisy construction zone than luxury hotel, making our stay uncomfortable.
disappointment regarding my recent stay. My wife and I have been loyal patrons of this hotel for over 8 years, staying 5 times in 2024 and 4 times in 2025. We even traveled from Sydney, Australia, because of our love for this brand. However, our recent experience has left us questioning that loyalty. First, the ongoing renovation has been handled poorly. Although I was informed the work would conclude by late February, the excessive noise and dust significantly disrupted our stay. More alarmingly, there was a serious safety lapse: my wife nearly collided with an electrical maintenance team while exiting the elevator at night. There were no warning signs or safety barriers in place. This was a dangerous situation that could have resulted in a severe injury. Furthermore, it is disheartening to see that despite the inconvenience caused by the construction, the Titanium member benefits have actually been reduced. Compared to other loyalty programs like ALL (Accor Live Limitless) or Marriott Bonvoy, the perks here no longer feel rewarding. As long-time supporters who cherished this hotel, we are extremely saddened to say that we no longer feel welcomed or valued. At this point, we have no desire to return.

A beautiful luxury resort hotel in the heart of the city
Anantara Siam is located in a convenient location very close to the BTS and many nice malls and eating place close by. It is a very beautiful hotel, has well appointed rooms coupled with great guest services. The hotel has good restaurants too. The breakfast buffet has a good spread of food across Asian and western cuisines. All restaurants are beautifully decorated and the food delicious. Special thanks to the excellent staff Mind, Becky, Bam n Kate for their welcoming and warm service at the club lounge.

My favorite hotel in Bangkok
I have been around to most of Bangkok’s five star hotels. When I summarize different points Anantara Siam wins much because of its staff, location and the big swimming pool.
