Tambo del Inka, at an ideal spot in the Sacred Valley, has this incredible pool.

I was asked to submit one hotel — just one! — for this roundup of Best spa hotels from around the world for Boutique Travel. It was not an easy pick!

I especially love spa hotels in north Africa with their hammams, and in Southeast Asia with their frangipani, ginger tea, and heavenly treatments.

Despite that, my pick for the article was from a resort near Peru’s Machu Picchu, with this spectacular indoor-outdoor pool.

I think I need to write my own article, though … I’ve been lucky enough to experience so many wonderful ones!

Where’s your favourite spa hotel?
