1. The Siam, Bangkok
Superlatives abound at this serene riverside stunner, where 28 rooms are positively suite-like and awash with antiques and Art-Deco-ness, blended with Thai influences. The Opium spa and 23m-long pool are impressive, as is the service, which is impeccable (and on the formal side). Dine on Thai haute cuisine at the riverside restaurant, or sip sundowners in the Deco bar. The hotel is quite far from the action of downtown but perfectly located for sightseeing in the historical Dusit district. Or let the staff whisk you along the river on the hotel’s very own golden teak rice barge, The Golden Naga.
