I think Couchsurfing is a great opportunity to get in touch with new people from all over the world. And of course it helps to travel with a low budget. The last months and years I made experience with Airbnb and I liked to stay with locals. It's quite more personal, you can get insiders tips and when you have a problem, you always have a contact person. Nevertheless in my opinion it's cooler to provide a bed for free and to have the option to sleep for free abroad. One hand washes the other:)

Hard to say.. I like HipHop, RnB, but basically I can hear almost everything. Movies I like are The Beach, Cast Away, The Boy in the Striped Pyjamas and Y Tu Mamá también. And I'm addicted to Narcos, Californication and Shameless.
