Traveller reviews

“Exceptional from arrival to departure and the memories love on forever.”
06 Jun 2025
The hotel is just stunning. We have always wanted to stay in a Bill Bentley designed hotel and this did not disappoint. The attention to every detail is exceptional and the whole experience is exceeded our expectations.

“Amazing stay at the most exceptional hotel you can find in Bangkok!”
07 May 2025
This hotel was simply amazing and the unique art deco style makes it a memorable experience! Staff was perfect and food really good. You also have a very nice swimming pool and view on the river. Besides the hotel offers free shuttles on their own boat to go to certain sites next to the river. The room was exceptionnal and the hall with the huge plants is simply stunning. You cannot forget this hotel. For us it would be the best hotel in Bangkok. Therefore we totally recommend this hotel for your next visit in Bangkok!

“Magical place, unforgettable hospitality.”

The Siam exceeded our expectations! It’s a very stylish and luxurious boutique hotel. We were surprised to have a dedicated butler who was available 24/7 and looked after us with great sightseeing and dining recommendations as well as travel arrangements. The hotel itself is full of incredible antiques and memorabilia with an outstanding private cinema room. If you are in Bangkok and want to be spoilt like never before, this is the hotel for you! We will be back for sure.

“A gorgeous, classy haven in Bangkok steeped in beautiful art, architecture and greenery.”

Absolutely perfect 4 night total stay at the Siam. The hotel property is just stunning, with gorgeous art deco architecture and filled with the family's stunning antiques. It has that personal touch which is so hard to find now in hotels (last time I felt this was the Villa Feltrinelli in Garda). The smell of frangipane greets you every morning as you go for breakfast. The food is superb and service is impeccable. Our butler, Gub, was excellent and made our stay so enjoyable with his recommendations and help. The Siam boat shuttle service was a wonderful way to get around Bangkok. We cannot wait to return.
