@Fred185 It sounds like you are a "Request to Book" host , as opposed to using Instant Book, if you are talking about hitting "accept". You can easily see a guest's profile before accepting or declining. Just click on the circle with the letter in it to the left of the guest's booking request message and that will take you to their profile.
But be aware that many guests' profile info may be out-dated (they moved and haven't changed the info on their profile, or they have purposely entered a place they aren't realy from). And where they are from, even if correct, doesn't give you any info about where they are coming from right now or where they have been.
