Anantara Siam Bangkok Hotel

A luxury hotel built around a 6-rai garden in the middle of Ratchaprasong — the trees and the lobby mural are the things you can't get next door.

In-Depth Review
Rooms and decor
Reviewers who stayed in a 47 sqm Premier room on the 19th floor describe contemporary Thai style with dark-stained teak floors, a headboard upholstered in gold Jim Thompson silk patterned with bullet-wood flowers, and a Lanna-style lamp hanging beside the bed. The private balcony looks out over the green Royal Bangkok Sports Club racecourse on one side and CentralWorld on the other. The marble bathroom splits the tub and shower, and the bath products are Anantara Spa from the group's own line. Expect roughly US$230–285 a night.
Food and amenities
The headline restaurant is Spice Market, set in the teak salon of the 100-year-old Phraya Prasert house — it feels like eating in an old aristocratic home. Reviews point to the beef green curry (around US$15) and the fried snakehead fish with fish sauce (around US$19), both punchy and properly Thai. Breakfast at Madison, the steakhouse, is a well-known buffet (about US$51) with eggs cooked to order. There is also the Anantara Spa and a fitness centre.
Location and getting there
The hotel sits on Ratchadamri Road, just 100 metres from BTS Ratchadamri, which puts the whole Skytrain network at your feet. CentralWorld and the Erawan Shrine are both an under-10-minute walk away. Suvarnabhumi Airport is around 45 minutes by taxi outside rush hour. The catch is the Ratchaprasong traffic, which clogs badly at peak times — the BTS is almost always faster than a cab.
Things to know before booking
Real-guest scores sit around 9.0, a small step below the very top of this list. Starting rates near US$230 a night are luxury-tier, with the best suites running past US$700. And the surrounding Ratchaprasong shopping district is one of the most congested corners of Bangkok at rush hour, so plan transfers around the BTS rather than taxis. None of these are dealbreakers, but they are worth knowing up front.
Our take
The thing you cannot get next door is the 6-rai garden — about 2.4 acres of 50-year-old trees and a 25-metre pool dropped into the middle of Ratchaprasong, where kids run the playground while parents sip a US$11 Mai Tai under the canopy. Pair that with the lobby mural and the Jim Thompson silk in the rooms, and Anantara Siam Bangkok Hotel is the pick for families and couples who want genuine Thai character without giving up the shops. We'd book it.

The Honest Verdict — pros & what to know
- 5-star from the Anantara group, with the polish and consistency the brand is known for across the region.
- Thai art and craft run through the whole hotel — the lobby is crowned by an 8-metre Ramakien mural by Chakrabhand Posayakrit, called one of the most beautiful arrival halls in Bangkok.
- 100 metres from BTS Ratchadamri and an under-10-minute walk to CentralWorld and the Erawan Shrine — you can shop the biggest malls and still walk home.
- A rare 6-rai garden (about 2.4 acres) sits in the centre of the property, with 50-year-old trees, a 25-metre pool ringed by palms and ferns, and a kids' playground.
- Spice Market serves real Thai food in a 100-year-old teak salon, and the 47 sqm Premier rooms come with teak floors, Jim Thompson silk and private balconies over the racecourse.
- Real-guest scores sit around 9.0, a small margin below the very top of this list.
- The Ratchaprasong area gridlocks at rush hour — lean on the BTS or budget extra time for a taxi.

Insider Tips
- Stop in the lobby to study the 8-metre Chakrabhand Posayakrit mural — it is genuine museum-grade Thai art, not hotel decor.
- Walk straight to CentralWorld and the Erawan Shrine; both are minutes away on foot, no taxi needed.
- Book a poolside seat around 6pm for a Mai Tai as the garden's amber uplights switch on tree by tree.
