I regret not having made a comment about this earlier, as I really think it's the best place to stay in Santiago. The staff are friendly, and it has a kitchen, a TV room, a living room, and two rooftop terraces where you can interact with the other customers. It's located in Bellavista, one of the most popular parts of the city. Take a room that doesn't face the street, as it can get quite noise. Highly recommended.
