Sanctuary Lodge, A Belmond Hotel, Machu Picchu

The only luxury hotel inside the protected sanctuary, sitting yards from the citadel walls, which means you get Machu Picchu in the late afternoon once the tour groups have cleared out. Rooms are comfortable rather than grand, and some patios open straight onto the ruins. Two restaurants, one reserved for guests. Nights run cold year-round, and the rainy season stretches November through March, so pack accordingly and don't say you weren't warned.
