I believe that you have to go local in order to visit and get to know a place properly. And there's no better way of doing that than couchsurfing. That way you'll have the time to talk with locals and be emersed in the culture. Specially far away from touristy hostels. I'm currently sharing a flat with a friend, so the decision of receiving people does not entirely depends on me, so that's the only reason I'm not and I can't receive people right now.
