Having a personal Butler, Pui, was a new and welcome experience for us. And a game changer in terms of enabling us get the most out of our time Chiang Mai. From helping us select tours and find our way around the city to serving as a single point of contact for room service, transportation, housekeeping and other needs, Pui was a huge help. She, Anne (GM) and the rest of the 137 pillars team are serious pros who clearly take pride in guest satisfaction and subsequently made our stay as relaxing and fun as it was memorable.
