Good morning!
I have two units I rent; both have separate entrances. What I have found is that having spaces that are not shared (due to covid) is idealistic. My state requires a Maine Covid Form to be signed which I have my guests do, I get to see who my guests are, and then hand them over the key. I can do lock boxes but then I do not get to see my guests. I like to interact with them 1. I want to see if they might be suspicious 2. I want them to know I am on the premises and they can check me out if they feel I am also suspicious 3. If they are breaking a house rule; dogs, other guests, etc.
I clean vigorously after each guest and let them know at check-in I do so. I have kicked one guest out due to breaking a house rule; cannabis smoking. Be polite about things, welcoming and make sure to CLEAN!! I found that is a huge thing and also no sharing is another plus!
Hope you get to experience a wonderful time with AirBnB, Good Luck!
