Photos are vital prior to accepting. A guest who has a "trashy" photo posted of them smoking or drinking is a good indication of how they will behave. If the first signal you send out as a guest is that you are a party animal or problematic in any way, g-d only knows what you will do when you are actually at the propety
Couple suggestions for you Sean. I rent out my guest house too and I am super careful about who I accept. What I do is
1) Mention in the listing that my wife and I live in the other section of the home. A party person would likely avoid booking with me knowing I live on the property
2) I am clear in my house rules, perhaps you may want to read mine under my listing titled "5* luxury boutique and its a decent deterrent or the link is here https://www.airbnb.ca/rooms/36105585?s=67&shared_item_type=1&virality_entry_point=1&sharer_id=561185...
3) I noticed in your description you mentioning that guests can have their own guests over for dinner. The problem with this is some guests with a relax interpretation may see this as an invite to have people over for "dinner" which may turn into a party. If a person is traveling as a tourist into another town, they often won't have friends there to invite people over for dinner. Thus this suggestion may be attracting more local guests to want to book your place. This leads me to my next point..
4) I rarely accept bookings from locals unless its for a good reason. Locals who read your description may interpret your house as a friendly home to bring their friends over which inevitably will lead to a problem that you will not have control over. Every bad experience when it comes to breaking house rules was the result of a local booking my place.
Lastly, there is a trick to seeing a profile picture before they book. It only works if they have a review and have left their previous host a review. You would have to look at the hosts property and the review they left their host and their picture would be visible
Hope this helps.
