Not many negatives, and i would definitely stay here again. However, just to mention, the room i stayed in had no windows and the air was slightly damp which resolved as soon as I opened the french doors for a few minutes. Most rooms have shared bathrooms and the ones with private bathrooms often book quickly - not necessarily a negative, just slightly inconvenient. There are roosters? on the premises which begin singing around 6AM (but that fits the theme of the Diaguita village and can be charming if you don't mind).
Amazing experience! The staff make this hostel perfect - especially Camilla and Carlos! Many staff members speak English. Even the ones who do not speak English are super accommodating and spend lots of time using google translate to help answer your questions. The facility is built to resemble a Diaguita village and this place becomes an oasis in the middle of the city . There are many shared living spaces which are very charming and rustic - many of them open to the outside and fresh breezes run throughout. There is even a fire pit with a fire that runs in the evenings. The staff will continue to add wood to the fire all night as long as guests are sitting outside. There are shared bathrooms for most of the rooms (although some do have private bathrooms). The shared bathrooms are all super modern and have showers (although it takes some time for the hot water to get going). There is breakfast that includes cereals, nuts, dried fruits, cheeses and meats including salami, and homemade jams. The hostel is located within the main city of La Serena (very close to the parks and shopping and buses/collective taxis) and is about a 15-20 minute walk to the beaches. Overall, highly recommended especially if you can snag a room with a private bathroom. Ask the front desk about the tours which they organize for stargazing and to the Elqui Valley which are great values!
