I was surprised to see the lost of poor comments about this place. As I read through them I suppose I understand some of the points, but not enough to warrant such a poor review.
The security doors do work, you just need to speak to the desk. The bathrooms are old, but are cleaned throughout the day and the water is always double hot. One of the sinks broke, but was soon replaced. The cleaners are always working, right now she is sweeping under my feet.
The dorms are a bit cramped and some of the mattresses a bit thin, but overall the lockers, lighting and clean sheets, towels are fine. We are talking about a €7 a night hostel.
But apart from the small grievances, the common areas and excellent staff make up for everything - they are super friendly, make you feel like family and make it hard to leave. I see so many people extend there stay by 2 more days, 2 more days. I returned after 2 weeks travel and saw the same faces, struggling to leave! I didnt mention the breakfast, pastries and coffee on table all morning to help yourself too. And the social evenings like Asado bbq and Epanada nights.
The one real downside is that the place makes you lethargic to get up and go!
