I had 2 instances were the lack of detail in the guest profile caused problems. First I accepted a guest.. the photo looked like a male and the name was foreign.. it turned out to be a female that was to share a room, had to ask another guest to share and give her the single room. I should not be having to do this. Second, I accepted a guest for 40 day stay, the profile said was a professional in finance and nothing else, on facebook and other research it turned out this person had history ofcausing problems for people by complaining to the authoroties about everything, so I cancelled... problem is that AirBnB BLOCKED MY CALANDAR FOR THE 40 DAYS! so I can't accept anybody else
