I have been coming to Bangkok for over 30 years and have stayed in many 5 star hotels. Anantara is the BEST---not just because of its location and facilities and food but thier staff is incredible---ever helpful and always smiling. I can't wait to return.

Anantara Siam Bangkok is a delighful oasis in the heart of Bangkok. The staff are welcoming and solicitous to all the guests, making everyone comfortable in their own way. The food was delicious. The pool was sparkling clean and surprisingly large for the inner city. We had a fun time breaking our return journey here. Thanks to you all. Cheers

Lovely hotel to come back to after a long time. It’s still the same. Nicely sized rooms with a huge bathroom with shower and bath. Wonderful staff who are courteous, professional and always helpful, willing to going to extra mile to make sure our stay was comfortable. My only comment is that the hotel is currently upgrading and refurbishing so the spa is closed although guest rooms have been opened up as an alternative. There is drilling noises in the background most days throughout the day, but I appreciate all this is necessary for the hotel to be maintained and improved.
