Hi guys,
Unfortunately I hadn't read those final few messages when I went ahead and relented, agreeing to be be at my apartment at 1am.
At 12:08 the porter called me to let me know that their car was parked in our garage, their luggage was unloaded, they had been up to the apartment, and were now waiting in reception! I was nearby and so they were in the apartment by 12:15... they had 2 children with them so I let them in and showed them around with no fuss. The two girls were lovely, although one of them ran straight through a fly screen within minutes of arrival!
We don't have a common language so I messaged them as always regarding the extra night and am still awaiting a response. I have started the reolution procedure with Airbnb, but as they are still in my apartment I am really worried about the condition they will leave it in.
They are due to leave on Monday so here's hoping that things will be ok.
