I'm a respectful guest who will keep the rental neat and clean, but I do like to talk and get to know the area that I'm visiting. If I'm going on and on, just tell me to shut it. I may travel alone but I may also travel with my life-partner, so don't worry if I am talking too much, he has not problem telling me to shut-it.
I think this website is incredible in that it allows host to create an income, meet new people, but you don't have to have long term tenants. You know that fish and guests both go bad after 3 days.
