Reviews for Anantara Siam Bangkok Hotel
Fantastic stay!
We are regular guests at the Anantara Siam, simply because it's a lovely hotel with the most wonderful service. We are always received with the utmost warmth and hospitality. The location is perfect. The hotel has undergone major renovations (almost finished) and the rooms and bathrooms are lovely now. We want to thank the staff at the Kasara Lounge, including Joris, for the wonderful reception and service, as always!

A Very Perfect Stay in Bangkok
Anantara Siam is a legendary hotel in Bangkok in term of very nice rooms, fantastic Food & Beverage, excellent spa and the World Class hotel staff. My mother and I stayed at a newly renovated Siam room and we confirmed everything was perfect, started with very friendly bell person. (Khun Roger) at the entrance of the hotel, very effective check-in & check-out at front desk staff, variety of F&B and the fantastic room. My mother had 120 minutes Aromatherapy Massage at Anantara Spa. Many thanks to Khun Thian, spa therapist, for her excellent massage that made good blood circulation and pain relief and took a very good care of my mother. The spa receptionist is also very nice and friendly, especially Khun Meen. My mother loved Anantara Spa because of Khun Thian and Khun Meen. Advanced reservation is highly recommended for Anantara Spa. Breakfast Buffet at Parichart Court was also our highlight of our stay, especially variety of foods and very nice iced coffee. Many thanks to Khun Atcharapirn, Chef at Noodle Station and Khun Rose for their excellent service, not only us but all guests. We strongly recommend Anantara Siam for a very perfect stay in Bangkok.

Gym membership fees off the charts !
Love this hotel for so many reasons - quality of product, Biscotti one that I go back to time and time again. I had seen that renovation had been ongoing at the pool and gym and must say it all looks super - that said not sure who made the decision to change this to an exclusive club - not sure how guests fair but 250 k THB for an annual membership ? I just don’t see it - good for those that can afford it (wish I could)
