I cannot recommend The Siam highly enough. Such an outstanding property! The inside is simply stunning. So much to see everywhere you look. But also backed up by a seriously great staff. Seamlessly working in the background, everything just gets delivered exactly as it should. Even the food is outstanding. Absolutely will visit again.

This Resort was absolutely amazing. The service was outstanding. It was our Honeymoon annd I anm so happy I picked this hotel. Our Butler Zul was so attentive and kind. He anticipated our needs and reserved the hotel boat for us to and from where we wanted to go and we felt so safe. The breakfast was some of the best food my husband and I have had and the afternoon tea was delightful. The pool was wonderful and entire decor of the hotel is something you will never forget as you feel like you are in a luxury zen boutique. Highly reccomend this hotel.

I don’t even know where to start on how amazing this property is! The property is exactly like the photos and the hospitality met expectations. The grounds are stunning, pristine clean, mesmerizing and creative. The art through the property was really neat to see and learn about. The food was equally just as great as everything else! We will be recommending this place to everyone that wants an upscale, safe, clean, flattering environment. Thank you Siam for everything.

Amazing hotel. From the moment you arrive you are made to feel like family.
The staff are all very friendly, yet professional and nothing is too much trouble.
The property is simply stunning, and yet very understated. If you want 'bling' go elsewhere, but if you want a beautiful hotel decorated with impeccable taste stay here
Nick and his team should be very very proud of what they have achieved.
We'll definitely be back

The Siam Hotel is a beauty, so much thought has gone into creating a space that is serene and comfortable, the decor is among the best that I have seen in hotels of this type, apart from the decor the staff are fantastic, two restaurants one Thai one Western, food is good in both, I ate in everynight, if I ever return to Bangkok I will return to the Siam

The Siam exceeded all expectations. The rooms were comfortable and well appointed. There are truly unique and thoughtful touches throughout the property that make it feel homey (a vinyl room, screening room and sitting areas for example). The decor is an impressively curated collection of southeast Asian history. We enjoyed using the gym including a private Muay Thai lesson and the spa including a private barber for my son. The private boat that takes you along the river to various stops is a huge perk to avoid Bangkok traffic. Probably our favorite part was enjoying a slow and quiet breakfast watching the river each morning. It was a lovely retreat from the Bangkok hustle. Our butler (Zul) was very attentive and took care of all of our needs.

An amazing hotel. Excellent range of food for breakfast with no buffet in sight. A few lapses in attention to detail regarding clearly stated dietary requirements, otherwise a very enjoyable stay.
Room striking design - huge, immaculate and well designed except no window to look out of - natural light does come in via bathroom window during the day. Bed and bedding superb with huge bathroom area and fabulous lighting. Interesting display of cameras show cased in room and many wonderful art and historic pieces on display in the hotel that we didn’t have time to fully appreciate.
We only stayed 2 days - not enough time to fully explore all aspects of the hotel. A plan of the hotel in room would have been helpful as not obvious where the various fitness rooms and bars were situated - we were only shown to our room on arrival at 6pm.
Pool excellent and plenty of sun loungers with lovely peaceful river views. Provided with iced water and towels, but also sunscreen which was so thoughtful.
Quiet and relaxed. Location not ideal if you wish to be close to popular areas, but by using the boat that will stop at jetty you require, can enjoy access to the sights yet retreat to the oasis of the hotel afterwards.
There is a ‘butler’ service - for the basic suite though this is really more of a concierge service but using watts app chat that mostly works well, although the butler was clearly unaware of all I had organised in advance by e mail.
Look for to a longer stay next year
