The Hostel is located close (15-20 min walk) to Gare de Lyon which was important for me. It is close to the Metro too, but it takes some time to walk to the city center.
It is a very modern building with toilett and shower in each room. I thought the bed was very comfortable. However there is currently a construction project next to the hostel which woke me up at around 8 in the morning (only mon-fri). A towel and a lock for the locker costs extra.
The staff is very friendly too. Perfect for a night or two in Paris.
