best hostel I've ever been, really good choice and cheap for Paris, I can absolutely recommend :)
really interested in giving you a good stay here in Paris and in the hostel.
I first booked a wrong dorm for men, they wrote to me and I was able to book a right one for women befor it's sold out.
No extra costs or something like that new booking/ for de change of the dorm.
I'm really enjoying my stay here.
