@Uigi0 I send a map to my place to my guests, PDF, as an email attachment. Go to the guest's reservation, scroll down the page until you see "Email". Under that the guest's coded email address that Airbnb assigns appears (actually it didn't until a few days ago, but it's showing on mine now). Copy that and paste it in an email address bar, attach the map to the email.
It doesn't always come through, especially if a guest is accessing their email from a phone. In that case, I ask the guest for their actual email address and attach it to that.
