I find couchsurfing can help people who like travels but need to save some money, and can be amazing to share experience and give advices to visit some place. Local people know a cool place to chill and try a good coffee, find a handmade market. Everything shared becomes better! I know a lot of friends and travelers that I met here advised me to do a couchsurfing...it's good to practice and improve the language!!!! I can also do the same in my country when I come back home ;)

Reggae, rock, dud step, techno (good one!), drum & bass... Books more a story based on a true event, history books...
