Absolutely incredible. Was very surprised.
I got the bed with 2 bunk beds, so 4 people. Comfortable beds with courtain for privacy, good AC and amazing bathroom.
In my opinion, the bed and the bathroom are both better than standards.
Outside area is also amazing, food and drinks are pretty good and also, the bar/restaurant is has some of the best reviews in Huacachina, which is great.
Related to that, the breakfast was good too.
The hostel offers a back passage to the path to the main point of Huacachina, with access to basically everything.
The roofttop is pretty nice, but it could be more useful hehe
