The highest score in this list at 9.5 — Mandarin Oriental is Thailand's oldest hotel, open since 1876 on the Chao Phraya River in Bang Rak. What guests return for is the Authors' Lounge, an afternoon-tea room in a white glass conservatory, and Le Normandie, the two-Michelin-star French room. River Wing rooms look straight down the Chao Phraya with boat traffic all day. It's about a 10-minute walk to Saphan Taksin BTS, but most guests use the hotel's free shuttle boat, which crosses to ICONSIAM in five minutes.
