Reviews for Anantara Siam Bangkok Hotel
⭐️⭐️⭐️⭐️⭐️
The staff, without exception, were all excellent. I was impressed by their communication and high-quality service from the hotel entrance to my room. From their smiles and morning greetings, to their smiles that extended into the evening with a "goodnight" greeting.

Wedding at Anantara Siam
We held our wedding at Anantara Siam, and the entire experience went far beyond anything we expected. Every department truly understood the assignment—and then delivered more than what we bargained for. K. Golf, our wedding go to person, took care of us from start to finish. She was attentive, proactive, and consistently went above and beyond to make sure we were happy. She delivered more than promised and made the entire process feel effortless. The head chef was exceptional. Not only was the food incredible—our guests couldn’t stop complimenting every single dish—but he was also extremely kind and accommodating. Vegan, vegetarian, food allergies, special requests—he handled every request with care and made sure every guest had something they loved. The flower & décor team, ทีมน้องน็อค, was amazing. They understood our vision instantly and executed it even better than we imagined. Their attention to detail was remarkable, and they delivered far more than what was agreed. The setup was stunning in every way. Overall, the team at Anantara Siam was professional, caring, and detail-oriented. Beautiful flowers, flawless service, incredible food, and a team that genuinely goes above and beyond. We honestly couldn’t recommend them enough. They made our wedding truly unforgettable.

Always wonderful
Despite living in Bangkok, I choose to come here as a mini break with a friend or my partner, and love it. Amazing breakfast, lovely surrounds, quiet, and very friendly staff.
