Couchsurfing for me is a wonderful opportunity to meet new people, make new friends, have fun in the cities you've never been. I have already used this application in France and it was really awesome. I suppose using couch is the best way to explore the unique atmosphere of the country as you live with locals who can tell you lots interesting things. Couchsufring is about networking, learning new staff, sharing ideas and thoughts, partying and having fun.

It depends on the mood and situation. I can't say that prefer something really typical. It is often influenced by the company:-)
