Bonjour @Jean-Baptiste135
I would say it depends on the type of questions you are being asked - are they questions once they have arrived on how things work in the apartment or places to visit, where to eat etc? If this is the case, a house manual in English and French is a great way for guests to obtain this type of information. I have a written copy but others use a digital version too.
If the messages concern questions on parking, transport questions, house rules, arrivals/departures, guides etc then the quick answers or programmed messages are your best friend😊 especially if you have many listings.
But difficult to say as you we don't know what kind of questions you are being asked. The description on our listing should be as complete as possible too and commenting on the photos is a good idea - size of rooms, beds, what's included etc as some guests tend to look at the photos rather than read the detailed description😉
Some guests need more hand holding than others, that's true but personally I feel it's much better to get asked questions before or during their stay and deal with any issue then find out they were missing something in their public comment!
Bonne soirée
Joëlle
