Reviews for Anantara Siam Bangkok Hotel

Our home away from home when in Bangkok

TripAdvisor Traveler Review Rating Reviewed 1 day ago

As returning guests, we were reminded once again why Anantara Siam Bangkok continues to be one of our favourite hotels in the world. From the moment we stepped through the doors, we felt immediately welcomed back—not just as visitors, but almost like family returning home. The hotel’s timeless beauty still amazes us: the grand lobby filled with orchids, the peaceful courtyard, and the elegant Thai design that creates a calm escape right in the heart of Bangkok. Our room was immaculate and comfortable, offering the perfect retreat after exploring the city. Breakfast remains a highlight—delicious, beautifully presented, and with an incredible variety that makes it impossible not to look forward to each morning. But above all, it is the people who make Anantara Siam truly special. Every staff member we encountered went above and beyond, combining professionalism with genuine warmth and kindness. Whether at reception, concierge, restaurants, or housekeeping, we felt cared for at every moment. A heartfelt thank you to the entire team—you create an atmosphere that keeps us coming back. Your hospitality, attention to detail, and gracious smiles make every stay memorable. We can’t wait to return again. Anantara Siam Bangkok will always be our home away from home. 🌸

Elegant living in Bangkok

TripAdvisor Traveler Review Rating Reviewed 2 weeks 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 2 weeks 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.
