We spent four wonderful nights at Anantara Siam Bangkok and were impressed from the moment we arrived. The staff were consistently attentive from the warm greeting at the entrance to the reception and the thoughtful service at breakfast. The location is ideal, right next to the BTS (though we mostly used Grab), making it easy to explore the city. While one side of the building is undergoing renovations, it did not affect our stay at all. It's worth learning about the history of the building, the inner garden and the large mural in the hall. Breakfast was a true highlight, offering a wide variety of delicious options in the serene setting beside the koi pond. Evenings were made more special by live music, elegant piano performances during the week and a vibrant band on weekends. Overall, our stay reflected everything we love about Anantara: refined, welcoming, and memorable.

Hotel Staffs super friendly, polite, and very helpful. Hotel Spa excellent place for a good nap relaxation place, Spa staffs extremely well trained in massage. Buffet breakfast is good, I would appreciate much if more Asian food be added to daily, Main entrance porter staffs well mannered, very helpful too. My 6days 5nights stay very well worth. Will definitely be back again soon. Thank you so much Anantara Siam Hotel Bangkok. Bravo

I had dinner at Anantara Siam a while back and it was a memorable evening. The restaurant had a warm and elegant atmosphere, with service that felt both attentive and genuine. The dishes were beautifully presented and full of flavor, clearly prepared with care. Prices were on the higher side, but they matched the overall quality and setting. Looking back, it was a refined experience and one I would happily repeat when in Bangkok.

We came in to buy their membership program but found out that we couldn’t buy it and that nobody had any knowledge because it’s a separate company we were planning on going to the café which might’ve had 50% discount with membership but couldn’t so we have to wait until Monday. Imagine running a fancy five star hotel, and not being able to sell a package because the staff don’t have knowledge? Unbelievable Simple solution: Train a few employees on the package so that anytime 24 hours a day someone can buy it Turning someone away because no one has any knowledge is really silly 😡 Package cost: ฿ 12,000 In a different country, people would yell at a manager & maybe they’d improve. I was so angry, I felt like yelling, but Not in Thailand 555
