Staff are fabulous as always and the room is spacious, clean and comfortable. Would appreciate multicountry plugs and USBC ports in the near future. Only issue was courtyard bar playing live music until 11.30pm on a weekday but it stopped not long after calling reception.

Pros: Great service everywhere - efficient and friendly. Very clean accommodations. Good amenities. Excellent breakfast buffet! Excellent location. Cons : No vanity mirror in bedroom. No good channels on t.v. - needs to have Netflix, HBO prime, etc. Spa was ok but facial was below par (not thorough, noisy, pushing product sale, etc.) In-room coffee creamer packet extremely difficult to open, so could not have coffee in room.

Amazing stay and hospitalities! It was my first time in Bangkok and Anatara has definitely given me an excellent memory! No complaints, the hotel was perfect for everything. There was a dress code to access the lounge and dining which I was little surprised however given the condition of the hotel I can understand that they might not want people wear flip flops to enter the lounge lol as lots business meetings are happening.

I never write reviews, but my stay at Anantara Siam is worth writing about. Great hotel — not so large that you get lost in a sea of tourists. Great amenities. Extraordinary staff. Son took ill and staff made sure we had everything we needed for him to get better. Would not stay elsewhere in Bangkok.

Hotel is very beautiful, even though building itself may be a bit dated. I travelled during the Songkran weekend, and the staff put up a parade - a completely "White Lotus" experience! The staff were very friendly too. Spa is amazing! Not sure if this is available, but may I suggest perhaps that the hotel provide free traditional costumes so that we can dress up and take photos with the beautiful staircase?
