@Trisha92 It's very difficult to get any personal guest info from CS. It's also difficult to get a straight answer that makes sense.
Profile pictures are of little use to any of us. A guest can look very different in person than they do in profile. The communication with the guest before and at booking will give you more clues about who you are dealing with.
I would be more concerned about the 'friends' arriving with this person, since your listing occupancy is max 2, and you address unregistered guests in your house rules. It seems this guest broke some rules. Was it a party? What did you say to the guest when you became aware of the unauthorized visitors, and what transpired after that?
