It has an amazing atmosphere and is very well located.
I got there really late around 2 AM, my flight arrived too late and the public transportation at night is not so good to get there from milano centrale. The staff was very comprehensive with my delay, I probably woke up the gentleman and he was still in good mood.
Actually is not a hostel, but an inn. We booked a room with separated beds for 8 and received 2 rooms with two queen beds each. Excellent price! Do recommend to those who travel in couples
