@Walter587 sounds like a scam and ANYONE asking for you to call esp. with a code of letters or numbers is doing something WRONG. Even through Airbnb they know you have can't send phone numbers - as that is against TOS terms of service. Everything on platform, that means on the Airbnb app. When they suggest you do otherwise. Drop them and flag them and stop communication. If they are persistent contact Airbnb.
Seems to me these last years since covid - communication has become much more strange, difficult and confusing. Seems people struggle to say what they mean to say.
Here's how I read their message until they asked you to call with the bizarre phone thing!
The husband is working in your town and the family is joining him soon and want to stay in your place and want to check a few things....that's kinda the underlying message, BUT then its clear if that were real, people don't want to pay service fees/taxes and will try anything to book off platform. Booking off platform is against all policies, TOS - and it is stealing from Airbnb. And if you or any of us do it we should be shut down. Airbnb is how these folks see our places and how can anyone feel it is OK to just cut them out when they put our listing out there for everyone to see.
So I'd call it a scam and have no part in dealing with these kind of people.
Glad you asked so others can also learn.
