I put in my house rules that their ID must match their profile. Personally I do not ask for their ID on arrival if I see that they are the ones in the profile, but I hope that the rule will act as a deterrent. Some newbies this year had a photo where they looked like college kids although they were in their fourties, so I suggested a more realistc photo of the couple. Not all hosts are keen on hosting college kids 🙂 Last year I had a booking from two pairs of feet, so I asked them to provide a proper photo. If they are unwilling to provide a photo of their face, now that would be a case for concern.
If the guests have nothing in their profile, you can also ask them to update and tell a little bit about themselves. It is better for all parties that the host/guest is a good match.
I get some clueless old ladies from time to time, you are likely to get the younger crowd looking for reasonable accomodation in an expensive country. An alternative to the hostels. I get those too from time to time, four young friends cramming into my apartment for the same price as beds in a hostel dorm, but only if I open up single night gap days in my calendar, never for my normal 3 night minimum. They are good guests though, without exception so far.
Some guests from certain countries in the far east are less well travelled, so I suggest you have a document with detailed directions. Due to high roaming costs they can also be reluctant to use google maps.
