"Rachamankha A stay at the adults-only Rachamankha feels like an extended visit to a supremely stylish friend’s home. Designed by interiors maven Rooj Changtrakul and renowned Thai architect Ongard Satrabhandu (who happens to be Changtrakul’s stepfather), the 24-room boutique hotel is inspired by 15th-century Lanna and features crisp white walls that offset Chinese antiques, vaulted wood ceilings, and colorful Thai silks. Serene courtyards give way to a library, an art gallery, and a poolside massage pavilion for low-key relaxation. Even the restaurant is primed to make you feel at home, serving regional comfort food like Burmese curry in an alfresco setting that reminds you why you booked here in the first place."
