Opened in 2010, the second hotel from quietly expanding Peruvian chain Aranwa is hidden away in a 16th-century colonial mansion beyond Plaza Regocijo. The stone walls, heavy wood bed frames, incredible collection of antique furniture, and oil paintings from the Cuzco School are reminiscent of better known pads but without the elevated price tag. The in-room highlights are without a doubt the marble bathrooms, which are some of the best around, with heated floors, Scottish showers, and deep soaking tubs. (Classic Rooms miss out on the soaking tubs, but are otherwise just as comfortable.) An intelligent oxygen system pumps in 30 percent more air than normal to the accommodations. Note that the layout of the historical mansion results in some rooms being smallish, or having odd angles.
