@Helen3 The guest this weekend clearly did it on purpose. He had his own pillow and blankie! Super awkward.
The woman who actually booked had said she was bringing a friend, but I assumed (since my listing is for 1 room/1 bed) that the friend would share the bed with her. I didn't make a stink because I was leaving for the weekend anyway, but if I had been around I would have asked the add-on friend to vacate.
The other couple "took over" the shared room by putting their belongings everywhere and closing the door as if it were their own private room! I politely let them know that was unacceptable, and they apologized and moved their stuff back in the rented room.
But seriously, why does this need to be explained??!
I have now added this to my house rules:
POSITIVELY NO COUCH-SURFING. Sleeping is not allowed anywhere other than the assigned bedroom, unless specific arrangements have been made with me in advance. When in the shared den and living room, consider how a reasonable person would behave in a hotel lobby, and act accordingly. Feel free to lounge, read, watch TV, have a drink, etc., but do not sleep on the couch or leave your belongings lying around. (I am sorry to have to post this rule, but not all guests seem to understand the concept of shared spaces.)
I'd appreciate any feedback on this...
