My partner and I stayed for one night at the end of our trip to Thailand and once we arrived at the hotel, we were just gutted we hadn't booked for longer. The Siam is honestly the most beautiful hotel we've ever stayed in. It's filled with incredible antiques (and an antiques shop!) and is styled to perfection. You can tell the family who own it have put a lot of work into making it so special. On arrival at the hotel we were greeted with a glass of chilled passionfruit juice, introduced to our butler, Wee, and greeted by Nick, the general manager. Wee showed us around the hotel, helped us make plans for our short stay, and then showed us to our room. We stayed in a Siam Suite which was huge and (as with the rest of the hotel) perfectly appointed. The bed was enormous and incredibly comfy, and the bath was a dream. We had a glorious swim in the pool, and delicious lobster rolls and cocktails at the restaurant. When we arrived at the pool, a member of staff put together a little tray with iced water, suncream and a fan for us! Wee helped us arrange the complimentary sunset cruise into the city, and gave us advice on where to get some good street food for our final meal in Thailand. Just before our cruise, Wee arrived with iced tea for us to enjoy on the boat - it's the small touches like that that make the Siam really special. On the morning of departure, because we were leaving before breakfast officially started, Wee kindly arranged a full in-room breakfast for us. This was really kind and just another example of the hotel going above and beyond. We really couldn't recommend the hotel more - we liked it so much we bought a copy of The Siam's coffee table book!

Dear aliceb1996 It was truly our pleasure to welcome you both to The Siam recently and thank you for sharing such amazing feedback here. It is true that 24 hours at The Siam is not enough time to relax and enjoy all that we have to offer. However I am delighted to hear that Khun Wee (our newest Butler to join the family) was able to ensure you had an amazing time overall. It's great to hear you took advantage of our scheduled boat cruise to head out an explore for the evening. Now that tourism is returning to Thailand, our boat schedule has increased to run five times a day, seven days a week so that definitely helps our guests escape Bangkok's notorious traffic! We hope it won't be too long before we are able to welcome you back to the riverside here in Bangkok. Needless to say, we hope it will be for a little longer next time....we will be waiting. In the meantime, warmest wishes from Khun Wee, myself and all The Siam family, Nick Downing General Manager

We stayed at The Siam for our 10 year anniversary and were blown away. The hotel is stunning. Every corner was a photographers dream. The attention to detail was out of this world - from the art of the wall, books in the room. The rooms were designed to perfection. Unlike other big 5 star hotels in Bangkok, The Siam oozes with character and is so charming. We felt like we were staying at a museum. The service went beyond our expectations. GM Nick and our butler Sumet was always one step ahead of us. They did everything to ensure our special occasion was memorable. We have stayed at some of the best hotels in the world would and would rarely say we would ever go back. I can safely say that we will be back at The Siam. Best hotel in Bangkok. hands. Down.

We have stayed in the finest 5 star hotels throughout the world. Never have we had better service and more attention to detail then at the Siam. This is a beautiful boutique hotel which we fell in love with. The Riverside room is beautiful. Nick, the GM, has a staff that is unsurpassed in terms of taking care of your every need. We have stayed at the large, beautiful hotels in Bangkok and we will always pick the Siam in the future. Do not miss the opportunity to stay here. It is truly fantastic.

It's hard to explain just how beautiful the Siam Hotel hotel is. From the moment you walk in the door it's simply stunning. Our arrival was first class - and before we'd even checked in, while having our cooling welcome drink, the General Manager had come over to welcome us personally. Our butler Gub was on hand whenever we needed, and the room we'd booked was absolutely outstanding. We didn't get to experience it for long, as we were given a very generous upgrade to perhaps the largest hotel room I've ever been in. it was simply gorgeous and we really didn't want to leave. Even the corridors and the balconies are mesmerising, the indoor pond and greenery in the huge lobby make this feel like you're outside even when you're not. The spa area was beautiful. The pool next to the Chao Phrya river is magical, and the food, the restaurant and the service was beyond excellent. And then you realise it's all built around a Jim Thompson teak house! Incredible. Make sure you look around. We were staying during Covid restrictions in Jan 2022 and so there were fewer guests than usual, which made our stay even more enjoyable. Thank you to Nick and the team for treating us to the most fabulous stay.

Dear timdownton A belated thank you for taking time to share such glowing comments and for rating us so highly following your experience with us earlier this year. I am obviously delighted to hear that we made such an impression. It is exciting to see tourism bouncing back now that restrictions are lifting. So I am sure you will notice more guests on your next visit with us....which hopefully won't be too far away. Until then, thank you again and sending best wishes from Khun Gub, myself and The Siam family. Nick Downing General Manager

The best luxury hotel in thailand. It’s fulled with soul and character of the owner who collected antique. The service is excellent. F&B is heavenly yummy esp lobster hash for breakfast. Absolute privacy. My favorite experience is spa by Khun Thong (Male therapist). He is one of the best therapist of all time.

Dear Apapan M Thank you for rating us so highly following your recent experience at The Siam. It is definitely true that The Siam has a collection of antiques, curios and artworks unlike any other hotel perhaps in the world. Our Owner, Krissada Sukosol Clapp has personally curated every space at the hotel with thousands of pieces from his personal collection. Part Hotel, Part Museum....The Siam promises an experience unlike any other. I am also delighted to hear you enjoyed one of our latest breakfast creations. I am proud to say that our range of breakfast dishes regularly earns praise from guests as "the best in town" especially as we focus on a la carte creations rather than the typical huge buffet approach of most hotels. And finally, thank you for highlighting Khun Thong at Opium Spa. We were delighted to welcome him back to our team recently and he has been earning much praise already. Thank you again Apapan M and we truly hope to welcome you back to our home by the river again soon. Until then, warm wishes from us all, Nick Downing General Manager
