Hosted loads for a while, a brilliant time. We were living somewhere unusual at the time, everyone that came through was interesting, intelligent and fun. Zero bad experiences. Made some friends for life.
My flatmate at the time ended up marrying a couchsurfer we'd hosted, after reconnecting many years later.
We all got sulky and huffy when they started charging and stopped engaging, but the sad thing is we just got too busy. Couchsurfing was like hosting a party constantly, and as work picked up I found it harder to engage.
Still seems to be a community there. I found myself in Split a while ago and stumbled upon a meetup, had a great evening unexpectedly.
