Hi I just booked a bed on airbnb. It is in walking distance for the warmup and for the main event as well. There is one bed left in the apartment. I can send you the link if you are interested. @odiestel
This is actually the list of questions I'd ask the person:
What is your name?
What is your story?
Where do you come from?
What are your interests?
Are you a party-person or a couch potato?
Do you like hackernews/designernews?
Are you a geek?
I'm right now looking at airbnb and couchsurfing.. nothing convincing so far..
