Perhaps the most charming guesthouse in Puerto Nariño, Maloca Napü has the look and feel of a tree-house fort, surrounded as it is by a thickly forested garden. The rooms are simple but comfortable, with fans, shared bathroom with super-refreshing rain-style showers, and fully equipped kitchen. Everyone who works here is above-and-beyond friendly.
Try for rooms in the red-and-black-painted back building; these share a balcony with hammocks overlooking the courtyard garden and jungle. Breakfast is COP$10,000 extra.
