The Pool at Chiang Mai Plaza Hotel

"The swimming pool is surrounded by Lanna-style pavilions, and their spa area is a catacomb in deep umber tones, dim lights, and Thai decoration, where the gamut of affordable but high-quality health and beauty treatments is on offer"

"Travelers who would prefer a more modern option with similar rates could check out the Nordwind Hotel, although it doesn't have a pool, spa, or fitness center"
