Hi there from experience once the booking is confirmed and there is 3-4 days before check in I usually message guest to ask them if they have any special requirements, confirm check in time and provide directions then
The reason I like to check with them just few days before as people schedule always changes 🙂
If it is possible for you, i see that a guest after a reservation takes outomaticlly your exact address from Airbnb. But, depend on reservation time, your conversation with your guest.......you could decide, at which time you could give your guest more explanation about your place direction, known places near it....an so on.
