Just to give my opinion and thinking of leaving the page I had wo issues guesting:
1) They guy that stayed first was a little smelly, I can understanding since he was ciclying for a while.
2) A second guest stayed three days, we went for a beer with a friend o mine and at the time of paying the beer he didnt make a move to pay it so I payed for it. For me was kind of rude, if he didnt had money he would have just to refuse go for drinks or at least let me know.
For this bad experiences I am thinking I want to host again.
