It's a hostal really hard to find. The guy who recieved us was not really helpful at all, besides the fact that the reception is only open from 10h to 18h (which it's not shown on the web site). So, if you don't arrive after that time, you'll be kicked out, LITERALLY. And if you arrive before 10h, you won't be able to book in (even if the reception guy is already there).
As for the room, there was no heating, and the beds were not comfortable at all. If you are lucky enough, you'll get to know Daniela -one of the people working on the hotel- who will help you and give you some tips about the metro, tram and bus all around Milan.
