The matchless and ageless Pen has it all: the location (towering over the river); the reputation (it’s consistently among the world's top-ranking luxury hotels); and one of the highest levels of service in town. Its stately rooms are an absolute delight to stay in, and a lavish breakfast at the riverside open-air restaurant provides the perfect start to your day.
If money is no obstacle, stay on one of the upper floor suites (from 14,100B) where you literally have all of Bangkok at your feet.
