I had a delay, sent the hostel a message and they didnt reply me. When I got there, there was a card for me hanging in the front door, but the card was not working. I called them, but, again, no responses. I waited for more than 40m outside at 3am, then some girls were leaving the hostel and opened the door for me.
Furthermore, it is inside a complex of building. Be aware it's a place to chill, no parties or places outside to talk and make friends.
They have a wifi room, which ia really good If you're looking for a place to work.
For the price, you can find better things in Milan.
