Thank you for your thoughtful reply. I love my property and I put a lot of effort into the cabin because I love to share the healing of the forest around me and want to make my guest's feel special and assure they have everything they need to have a relaxing stay.
A sign is a great idea. I'm so new at this, I have a lot to learn. I was most upset to be woken in the middle of the night! But I totally should have had more communication with my guest and I will in future.
They did not seem tired, Linda and they have come back every night at 2 AM. The best thing about Airbnb is they only stay a short time and for the most part I have had lovely guest's.
