I got a room behind the reception. I could hear everything they said at the reception. I Did hear that there were many who complained about noise. They have paper thin walls.
Too noisy. Too expensive (70 eur)
There are much better hostels (one located in the city center but in a more cosy area), is Hostal Montaloya (price 45 eur).
A must for this hostel. Earplugs
