I have a holiday cottage that I rent out, and looking for some advice. a family has contacted me to see if they can rent my cottage for 2 weeks. They are being repatriated from Argentina in the next week, but cannot return home yet as there is a vulnerable person at their home. They want to use my cottage to self-isolate for 2 weeks. I can’t find a definitive answer on the government site to see if I’m allowed to do this, so wondered if I can do this?
