The location of the hostel was great - right in the city center. The staff was also very helpful and even called us a cab for a pickup at the hostel when we had an early bus out of Salta. On this morning, they also made sure breakfast was put out for us before we left at 6AM (breakfast isn't normally served until 7am). I thought this was really nice of them!
We stayed in a double private and the room had no windows are really poor ventilation so it got incredibly stuffy at night. The bathrooms were clean but the floors flooded easily, so you were always walking through massive puddles when in the bathroom. It was also advertised online that breakfast would be served with fresh fruit, which they never had. They only served croissants, cereal, and coffee. Pretty basic but we survived!
