It used to be that once a booking was confirmed, you could send personal details such as phone numbers, links addresses etc. I think there is a bug in the system as I somehow find it hard to believe it is intentional or the logic of it.
I had noticed over the last few weeks, that some of my messages containing URL’s or phone numbers were blocked whilst others went through.
I normally send a street map showing direction from the nearest train station to my place since lots of guests do not have Wi-Fi immediately on arrival, the can print or take screen shots. Also I send short term luggage storage links (yes guests can look this up for themselves, but it’s easier for me to do this than a foreigner since I know the city better), as a result of Airbnb blocking these details, the first experience the guest has Is sometimes a bit stressed trying to locate a property in a foreign land.
I understand not being able to exchange information prior to the booking but once it has been booked and paid for, the guest has my address and that’s the biggest safety detail to give out, I don’t see how an additional phone number of a URL can possibly be a risk at this stage….
Anyway Marty, I’m sorry, my little rant does not help your predicament so back to the issue, perhaps contact Airbnb and ask them to get the details for you since they are blocking communication, yes you have the phone number but it's expensive to make international calls.
Hope you get it sorted.
