Reviews for Anantara Siam Bangkok Hotel
beautiful stay
We have chosen this hotel several times because we have always had a great time. The staff do a fantastic job, constantly working to ensure that every guest's every wish is fulfilled, and they are also extremely nice and friendly. The hotel is beautiful and sophisticated, very well located, easily accessible and with lots of things nearby. I can also recommend the restaurants. We had a delicious meal every time. It is always a pleasure to return to this hotel. I can only recommend it. For me, if it's Bangkok, it's Anantara Siam.

Wedding Reception Joys at the Anantara Siam
We decided to go with the Anantara Siam Hotel for our wedding reception for it's location, atmosphere, and engaging staff. It felt luxurious, while maintaining the Thai charm that felt inviting at the same time. We were recommended by friends and have no regrets as the staff were very hospitable, flexible and attentive to our needs despite many changes that came up with planning from overseas. A special shout out to K'Golf who supported us throughout the planning process and was very responsive throughout. We stayed there for two nights, along with several family and friends as well who all enjoyed their stay especially the breakfast buffet and food prepared. From the beautiful flowers and set up, to in-room surprises and warm welcome, we had a beautiful celebration to last down memory lane. Location is easily walkable to several major malls like Central World, Central Embassy, Chid Lom and Siam Paragon. Although the pool was closed and the hotel was undergoing several renovations this summer, they also provided the use of the pool in the hotel next door and ensured no renovation would take place during our celebration.
