I've added some info to the wiki page.

https://wiki.unsystem.net/index.php/DarkWallet/Meeting_Nov2013

Everyone has different dates so people will be arriving and leaving
throughout the next 2 weeks. After 2nd December, there will be public
events so if anyone who is around can present to general public about
any topic they want to talk about.

It's the cold winter now in Milan, and lots of people are arriving. Take
a warm jacket, and if you can bring sleeping bag/blanket then there
should be enough spare blankets for people who don't bring anything.

If you arrive to the place, you can knock the door and enter. Just say
you are for the Bitcoin meeting.
