Anantara Siam Bangkok Hotel

The interior design and style

This hotel impressed on every level. An excellent building with spotless well-appointed rooms and superb staff. Food was fabulous.

My elderly mother and I recently returned to the Anantara Siam to commemorate a family anniversary. We had previously stayed two years ago (see review 21 February 2024) and before that I had visited with my husband (see review 31 January 2023). To say we all absolutely adore this beautiful hotel, its facilities, and its staff, is an understatement! This time was a little different as the hotel was only full to 1/3 capacity due to ongoing renovations, yet the renovations were entirely behind-the-scenes and caused no disruption. It was inadvertently the perfect time to visit, as the best public spaces - the lobby, pool, gym, Parichart Court breakfast area, and Kasara Lounge - were able to be enjoyed with no crowds of guests! The newly reopened pool, with its the red umbrellas and black & white tiles, is totally stunning, and the Kasara Lounge has had a nice contemporary update. As ever, the staff complete the wonderful ambience of the hotel as a whole - this time we were particularly looked after by Kate, Mind & Lyn in the Kasara lounge, and also Kae & her capable team at the main breakfast buffet. We look forward to our next visit and would not stay anywhere else in Bangkok.

My wife and I just returned after spending three nights at Siam Anantara Bangkok.
The service is par excellence. The staff is very courteous and goes out of the way to help you in every way.
The rooms are fantastic, big and clean. The location is very ideal because it is very close to Major Malls.
We would like to appreciate our thanks specially to few people from the hotel.
The General Manager was so helpful that he even went out of the way to introduce the chefs of the hotel for our special vegetarian meals.
The concierge Ms. Jam (Tawaree Sommanasak), who was so helpful to make our stay comfortable in every way. She is so courteous and gave us lot of information as we were visiting Bangkok after many years.
We also want to thank Mr. Tan at the reception counter for helping us on the last day during our check-out by making everything easy for us.
We give 10/10 points to Siam Anantara Bangkok.
Thankyou for everything.

Always a pleasure to return to Anantara Siam, one of my favourite hotels in Bangkok. Prior to arrival, I received an email informing me that GHA Titanium members are not entitled to lounge access, which was reasonable, as this has never been an included benefit. That said, it would be wonderful if GHA reconsidered this perk for their elite members in the future.

While I did not receive a room upgrade on this occasion, I was thoughtfully offered several alternatives to enhance my stay. These options were a lovely touch and allowed me to enjoy different aspects of the hotel that I might not otherwise have experienced during a short visit.

My room on Level 5 finally offered a lovely golf course view—much appreciated after mentioning a viewless room during my previous stay. Tan handled my check-in smoothly and was warm and personable throughout. Rowan kindly escorted me to my room and provided a helpful refresher on the hotel’s facilities and operating hours.

One small disappointment was the absence of a welcome amenity. It seemed to have been overlooked, as the table in my room (Room 505) remained empty throughout my first day after check-in.

I visited the Anantara Spa and had a wonderfully relaxing experience. Breakfast, as always was a highlight—warm greetings from the staff and impeccable service truly showcased Thai hospitality at its best.

The lobby’s centerpiece featuring the horse is absolutely stunning. I love how serene and calm the lobby atmosphere always feels—it never fails to give me a sense of peace.

The porters and the lady at the entrance (my apologies for not catching her name) were consistently friendly and helpful. A special thank you as well to Arbell for the smooth and efficient check-out process.

Overall, it was an almost perfect stay, save for the missing welcome amenity. I look forward to returning again next time!

The hotel’s location right next to a BTS station made it very easy to get around Bangkok. The staff were extremely attentive and helpful. Our room was nice, spacious, and clean. The breakfast and other occasions at the Kasara lounge were outstanding. The room was quiet and we slept very well.

Great location in the city centre only 100 metres from the sky train, with the most friendly happy staff you will ever meet.
The breakfast here is truly fantastic catering for all cultures, and with the calm oasis of the pool to relax by after exploring the city, this is a wonderful hotel.

Location and cleanliness

Excellent property with great location and awesome staff. Loved the dining options and kids club facility.

I have never had better service that at the Anantara Siam Bangkok
It is a truly exceptional hotel giving the best of service
I am a tough customer of hospitality establishments. But I would say this is probably the best service I have ever received

Anantara Siam remains my top choice whenever I travel to Bangkok for business. I return to the city regularly, and this hotel consistently delivers an experience that stands out.

The blend of classic Thai elegance and attentive, understated service creates a sense of calm that is quite remarkable given the hotel’s central location. Surrounded by the energy of Bangkok, the property itself feels composed and gracious, offering a welcome contrast to the pace outside.
Its position is exceptionally convenient—adjacent to Lumpini Park and ideally situated between Silom and Sukhumvit. With two BTS stations within easy walking distance and a wide selection of restaurants, bars, and rooftops nearby, getting around the city is effortless.

What I appreciate most is how tranquil the hotel feels once inside. The service is polished and reliable, the recently updated gym and pool areas are excellent, and the working environment is well suited for business stays, with strong Wi-Fi and comfortable spaces to focus.

Dining is a clear highlight. The overall food quality is high, and the renowned Sunday Brunch continues to be among the finest in Bangkok, offering an impressive selection of premium seafood and classic luxury staples.

This was my second visit in 2025, and I already have plans to return again soon. A warm thank you to the Kasara Lounge team for their consistently attentive care, as well as to the gentleman outside the hotel who kindly offered a cold towel and water after my morning run in Lumpini Park.

Anantara Siam combines location, comfort, and service at an exceptional level. It is always a pleasure to return, and I recommend it without hesitation.

The pool area had been redone and is beautiful.
