A lot of my friends have told me about Couchsurfing and what they've said really got me hooked. When I've been travelling so far, I mostly stayed in hostles. That is all the comfort I need and you can often meet some other travellers, but the places I enjoyed most where allways when I would stay at someones home. If it was friends, relatives or friends of friends (of friends) didn't really matter: I just love to have this sneak peak into other peoples live, to see the place you are visiting through their eyes and maybe explore some of there favorite spots that you'd miss otherwise. As I understand it, Couchsurfing is exactly that just that you don't know the friends you are visiting, yet.
