We had a spectacular 7-day stay at Anantara. Impeccable 5-star service, awesome breakfast, comfortable rooms, timeless elegance, and perfect location. There are beautiful design and thoughtful touches everywhere you go. The restaurants are top notch. You can’t go wrong staying here! We’ll certainly be back. I spent hours sorting through Bangkok hotels and I’m so glad I picked Anantara.

We spent the second week of our business/vacation trip at the beautiful Anantara Siam Hotel. Upon arrival, the hotel looks wonderful with the pond, white elephant features and the friendly lobby staff. It was delightful to walk out of the blazing sun and into the hotel that was fully air conditioned. The lobby is beautiful and the seating area is so comfortable. The front desk staff are absolutely fantastic!! The bags were sent up to our room so you don’t have to drag them along. The room we had was spacious with 2 queen beds, a desk, luggage bench and a seating area and the amenities were top notch. There is also a beverage station available with a mini fridge. We ordered some meals via room service and it arrived in style with a tablecloth, crockery, cutlery and a very friendly waiter. The food is presented so well and it feels so luxurious. Breakfast is served over 3 restaurants buffet style and the choices are mind blowing. We attended the conference at the hotel and the evening was awesome. The pool area is huge and it is ideal to lounge about and relax for the day. Food and drinks may be ordered poolside from the bar area. The Anantara Siam Hotel is absolutely beautiful and I had an amazing stay there!! Top class and top service!!

With so many hotels popping up all over Bangkok, and the quality and offerings increasing year on year, you might think it impossible for the older hotels to compete. However, this hotel shows class in its aging. Some hotels I’ve been to in Thailand look tired over time. This hotel looks distinguished. The staff, as you would expect, are dressed and behave impeccably. You truly feel special in this hotel. Location is perfect and the rooms are both elegant and clean. I thoroughly recommend it and will definitely return. A genuine quality pleasure.
