Seems there are two categories we are addressing. First is responding to inquiries where we do get the same questions repeatedly, in a variety of forms. I am working toward a template response that addresses each topic in a short paragraph, and I can omit the items that are not relevant. I save it as a Google Document on Google Drive.
Some standard topics for us include: DECORATIONS | TABLES/SEATING | CAPACITY | MUSIC | FOOD | ALCOHOL | PARKING | EARLY ACCESS | SITE VISIT | etc. The beginning and ending paragraphs are personalized.
The second type of FAQ is for guests who have booked. Like others, I have created documents that walk them through details of the space, rules, floorplan, etc. I email as PDFs upon booking, and have them printed in a binder for them in the space.
