As part of the Kempinski Group of hotels, this is one of the newer 5-star hotels in Bangkok. It was established in 2010, designed by Hirsch Bedner Associates and is located at the heart of Bangkok. The hotel has a touch of European contemporary sophistication alongside many Thai-themed services and cuisine. The Siam Kempinski has 42 suites and a total of 303 rooms, in addition to the 98 serviced residences. The meeting rooms offer an impressive welcome to delegates – each is accessed via an ornate golden brass door. There’s also a sumptuous spa, three dining areas, bar and gorgeous outdoor pool. But its highlight has to be the green royal garden accessed right from the balconies of the rooms.
