I think Couchsurfing it's a good option to someone who loves travel but don´t have money. With this, you win more than a "free sleeping", you win know someone who could show you the local culture and other things, you could make a friend (something much more important than save money). Open the doors of your house it´s necessary to this be a reciprocal relation and to make of this a nice cycle.

I listen reggae, hip hop and rock.
