Hi Guy, Firstly can I say what an amazing listing you have...I am sure you are going to have great success with your hosting offering quality of this standard!
As to your question, you say you have accepted your first booking! To confirm this booking go to your messages on your listing page and you will note a message stream with this guest. The first thing you will see is 'Up-coming Reservations' and the guest will appear in that box. On the right side of that box will be a tab which says 'Print Confirmation'. By checking that line full details of the guest booking will be displayed including amount details and a booking confirmation reference number.
I would not be too concerned if you haven't heard back from the guest at this stage, they may be travelling and find it difficult to respond to you just now. It may be worthwhile to message the guest and say...'because of the extensive nature of the property and the grounds I require **** days notice of your arrival time so I can make all necessary preparations for you'!
Good luck Guy, you have previous experience just follow your gut feeling and I am sure you will be successful!
Chers.....Rob
