Hi @Heidi125, the question is, what the hosting brings you. From what I read in your messages, you would prefer to have easy guests, who keep to themselves and who you do not need to entertain. Greet them, maybe smile when you cross them, and be paid would be fine. there may be days, where hiding in your part of the flat would be even finer.
That does not seem unachievable to me - I do a lot of work to filter out the taciturn keep-to-themselves types and get more of those you do not want. It should work in the other sense too.
You could rethink procedures: can checkin be automatic or at least very formalised? Greet them, here is the key, here is the room, here is the info) (In such a setting, the info should be easy, maybe pictures or illustrations.
Can you split the apartment in a way to favor not crossing guests? That could be a private bathroom for you or for the guest or at least a water kettle and some cups in your room. I removed a lot of annoyances in a tiny apartment, when I added a sink, an espresso machine and a water kettle to my room. Some snacks too: if the guest is not my cup of tea, I have my own breakfast or a soup for dinner without crossing the common space.
I do have a seperate entrance, but firm shedules might help a bit already. Reduce the time they can be in the apartment. If they need to be home, they will ask and you can "compromise", that they stay mostly in their own room. Better than being waylaid whenever you show the tip of your nose.
Longer stays might help too, to reduce the number of checkin prodcedures and cleanings. Maybe increase the price and add a five day reduction. My five to seven day guests ask nicely, if they really have to be out during the day every day and I concede an exeption for the week-ends. Both sides are happy - 2 years ago, I climbed the walls, if I had work to do and a seven days stay at home all day guest.
To filter for your kind of guests, you need to adapt the listing. Pictures and texts should be appealing to solitary taciturn people. Fast Internet, a big TV, movies, books etc, whatever attracts a person who likes to stay alone or be online all the time.
