Bangkok's newest boutique hotel, the Siam, opens this month with a distinctive blend of modern and traditional architecture and inspired design, courtesy of Bensley Design Studios. The 39 art deco-style suites and pool villas enjoy a coveted riverside location and feature the Thai owner's extensive collection of art and antiques. The hammam-style bath house (with covetable Sodashi products), library, cinema and traditional Thai tea garden set a new standard of decadence. And The Siam offers the first Muay Thai boxing ring ever to grace a hotel. For an even more authentic Bangkok experience, there’s also the option of staying in a century-old house once belonging to silk-trader Jim Thompson.
