I have just recieved a request from a person called "Ivan" from China for a room at our bnb in NZ, it would be our first from this area and unusually because he is asking for 10 days in June which is far longer than normal and also out of season? he states he is new to Airbnb and has no details added or recommendations with only an upside down picture and a partial selfie so blurred you can just see a rough shape. What is the best way to proceed and what safeguards should I take. I am very nervous about pre authorizing such a request with no history. All advise welcome
