One of Medellín's original hostels and still one of its best, this well-run and welcoming place is conveniently located and has a pleasant social vibe without being rowdy, but there are frequent lines for the too-few bathrooms. There is a variety of common areas, including a lovely terrace, and a good selection of comfortable, modern, private rooms.
The knowledgeable staff are particularly helpful in arranging tours, activities and onward travel.
