Having booked a double room by email we arrived after an overnight bus journey to find that our reservation had not been entered into the system. The reception staff were thoroughly unhelpful in sorting out the problem and we ended up staying elsewhere.

The lockers do not lock and there is no secure luggage storage. The communal areas are small. In comparison to other hostels it is in the top end of the price range, thoroughly without justification.

From our first contact with the people from the hostel we´ve got a good feeling, they were very helpful, not only with the reservation but also with the things to see and do in Rosario.
Upon arrival we were received by one of the owners, Flavia, she was really niced and showed us to our accomodations, and from them on we´ve only had fun.
Everyday we´d arrange difference things to do arround the city or great parties at the hostel terrace.
Regarding the bulding it´s a prety cool place, it´s an old recycle house with all brand new goods, which is really hempful when getting a service and using it´s common areas.
The bedrooms are really spacious, so shearing the room with others wasn´t a problem cause we had plenty space.
Last, but I think the most important thing, was that we could stay latter than in other hostel, so we could sleep longer =)
So if you ever decide to go to Argentina, and get to know this fantastic city, stay at Achuma hostel, is GREAT!!!!
