Reviews for Anantara Siam Bangkok Hotel

Elegant living in Bangkok

TripAdvisor Traveler Review Rating Reviewed 2 days ago

My always feel at home hotel in luxurious city living of Bangkok Stunning property in the heart of Bangkok city, very great accommodation, cleanliness is a key. The people there nailed the service very friendly and helpful with smile 😊 Would say I love the FB outlets as so many choices and of course top restaurants is inside the hotel. Distance to everywhere very easy just few steps to the sky train plus the area near all the biggest shopping center. ✅ breakfast line was amazing I think this is Top of Anantara standard Thanks to Remi and Khun Kae for her hospitality! ✅ my warm welcome from Mr. Torsten and Khun Narisa Definitely be back for my next Bangkok trip 🥰

Luxe green oasis in heart of Bangkok

TripAdvisor Traveler Review Rating Reviewed 6 days ago

Anantara is a real oasis - full of lush greenery, koi ponds and a beautiful large pool area. Plus a great breakfast and excellent service. Our unrenovated Deluxe Heritage Room was perhaps looking a little dated design wise Vs newer rooms but still very comfortable, and the hotel overall is a beautiful place to stay. Location is convenient for BTS and can walk to malls, hotels and lumphini park but no real standalone shopping or restaurant streets nearby. However, most big hotels are in similar locations in Bangkok. Only gripe is that while airport pickup is convenient for a speedy exit, it is wildly overpriced - THB2800 vs 500 for taxi. Perhaps hotel could consider a more reasonable option. Service was great - concierge Jam and George on the door team were both very helpful. Overall a great stay - recommended.

Celebrating the festive season with my family at Anantara Siam was truly worthwhile and unforgettable.

TripAdvisor Traveler Review Rating Reviewed 1 week ago

During the year-end festive season of 2025, our family chose to celebrate at Anantara Siam. It began with our daughter joining the gingerbread house decorating activity at MOCHA & MUFFINS, which she absolutely loved (this was already her 2nd time participating). Then, on December 24, we joined the Christmas Eve Dinner, where the Lobby was transformed into an impressive buffet line featuring a wide variety of dishes. Each menu came from different outlets within the hotel, and every dish was delicious, made with very high-quality ingredients. The overall vibe of the event and the performances were far from boring. The most outstanding part, which deserves special praise, was the dessert section. Chef Aey personally took care of the station throughout the evening—kindly recommending desserts and serving them himself. The station was beautifully presented, the desserts were exceptional, and we were truly impressed by the Chef. I would highly recommend the buffet here, as it will surely bring happiness to you and your loved ones. As for our stay, all the staff took excellent care of us—absolutely flawless service. We learned that many rooms have already been renovated, although the room we stayed in may not have been renovated yet. Nevertheless, it was still in very good condition and fully equipped, as expected of a five-star hotel. Our room was on the 2nd floor, conveniently close to the Kids’ Club and within easy walking distance to the swimming pool. We also enjoyed walking down the stairs to the lobby instead of using the elevator, simply to admire the beautiful mural paintings by Tan Kudt. During our stay, we had Japanese dinner at Shintaro, where the ambiance and service were excellent, and the food and ingredient quality were outstanding. (In fact, from my experience, you can dine at any outlet here and be satisfied—it really depends on what type of cuisine you are in the mood for that day.) For breakfast, there was a wide variety at the buffet line, including Thai dishes. On that day, Tom kha gai and clear pork rib soup were served—both were extremely delicious. After check-out, we enjoyed A White Christmas Afternoon Tea at the Lobby Lounge, which was beautifully presented and delicious. Once again, Chef Aey personally served us and explained the ingredients in detail. All of this made our time at Anantara Siam during this year-end season truly one of our family’s Unforgettable Journeys. P.S. During breakfast, I had a minor accident and cut my finger on a sharp object. The staff at that area were extremely attentive and took excellent care of me. Within a very short time, a nurse arrived and properly dressed the wound. As a result, I had a White bandage on my finger, which amusingly matched Anantara Siam’s festive theme for this year, “Legacy in White.”

A failed attempt at best

TripAdvisor Traveler Review Rating Reviewed 1 week ago

We stayed 3 nights arriving late by hotel car from overseas to be greeted at check-in by an incompetent staff member Unable to upgrade our room (I paid upfront 3 months ago and you knew I was arriving at midnight) due to occupancy and we are titanium level discovery member, stayed in a river front suite at their Anantara riverside last year, which was great It was too late to ask to went to our room, not escorted(not sure what else you have to do at midnight) No notice is advised of the ongoing renovation, and only unrenovated rooms available This was a bit disappointing On the second day we asked the manager in the lounge if we could change rooms at all and were happy to pay additional costs which they accommodated. The restaurants and bars, were refurbished a few years ago and generally have live music which is nice but nothing memorable. The pool was recently opened and was great to relax and tastefully done, note no sun in winter until 11:30 I have stayed in many hotels surrounding this place for 2 decades and after visiting riverside last year I thought it would be a great option. I cannot recommend this hotel, as nothing is delivering what it should as a 5 star.
