DSS lives a long way away, but is visiting this weekend as the team he manages has a fixture in our town. He rang DH this morning to ask if 4 team members could stay with us too, as their accommodation has fallen through. I wasn't keen as I don't know any of them and don't really want 4 teenage boys in my home. I contacted a work colleague who lets her flat through Air BnB and she agreed a good rate. Sent the details to DSS. He has now texted to say can they all stay here anyway, as it would be cheaper. It's three nights. AIBU to say no?
