Well you did the right thing by referring her to the house rules before accepting her booking request. Our places are very similar and I have found that many guests will not divulge the total number of guests unless asked to specifically list the ages of all infants.children and the number of visitors.
If you have a blurb about your surveillance cameras in the house rules, then that is great. I believe you even have a picture of them? Another suggestion is to note in the house rules to confirm something when making a booking request. You could say something like “I will be able to accept your booking more quickkly if you list the ages of all children/infants and the number of visitors that you will have during your stay.”
So for example, let’s say a booking request comes in that says my wife and I want to book your lovely home for our 10th anniversary. You could reply back with “thank you for your inquiry. Before I accept your reservation, please confirm you have read the entire listing description/house rules as I am unable to cancel a booking once I accept. Also, will there be any infants/children in the group or just the two of you? Also let me know if there will be any visitors during your stay. As soon as I receive your reply, I can move forward with the reservation. Thanks”
Most of my guests do not read the house rules before booking. I even have a note for guests to confirm that although my listing is noted as child friendly, that it only means I accept children; ;however, the house is not child proofed and does not provide baby gear, etc.
Once in a blue moon I get a guest who says “I have read all your house rules and am fine with them, etc.” - when making the booking request.
I specifically do NOT ask if the guest “plans” to have any visitors. I specifically ask for the number of visitors. It’s too easy of an out for a guest to come back once in your house and say “well I didn’t plan to have anyone else at the time.”
Feel free to PM me also.
