If you've spent any amount of time talking with your wanderlust (or tech savvy) friends lately, there's a very good chance you're familiar with Airbnb, the site that is revolutionizing the way people experience new cities. Simply put, the site allows travelers to avoid hotels during their voyage by instead putting them up in rooms, apartments, houses, castles, houseboats, igloos, and every variation of shelter in between. And since travel and beer are two things that are inextricably linked, the site makes a great resource for any hop heads trying to hit the road.
