As you have instant book turned on for each of your listings the information you wish to change may be included in the message that's sent when a guest instant books.
If that's the case you can change it by clicking on "Host" and selecting "Listings". Then click on a listing and click on "Booking settings". Then click on the "Edit" button in the "Guest requirements" section. Then check the "Guest trip information" section and click its "Edit" button to make changes if the information is there.
Repeat the above for each of the other listings.
If the information isn't there it may be in the house manual.
Click on "Host" and then select "Listings". Click on a lsiting and then scroll down to the "Guest resources" section and click its "Edit" button to see the house manual section. If this is where the information is, change it and then repeat for the other listings.
At the suggestion of your super host input, we have created a comprehensive House Manual, with all the necessary information on our condo, the surrounding area, suggested restaurants, amusments, museums, etc.
We know from the comments of our guests and questions asked us, that the House Manual is often not read, or just skimmed, usually in error.
Any suggestions on how we can reach our guests in a clear and precise manner?
