@Monika2, so sorry for you that you had two guests in a row leaving dreadful reviews. Or better: I feel with you, I had that over the holidays too, but some nice since.
I don't think that the bookings suffered because of that, rather that you are another vicitim of "the black hole", periods with nearly no views and bookings, which seem to happen since October to many hosts from time to time for shorter or longer periods. Even to superhosts with no recent dumpings. My average revenue on the room listing since October is 2/3 of what is was before, whilst I should have had no less guests with all the professional travelers in autumn / winter.
There are some crazy persons out there, loosing keys and breaking down a door. I had mine saved by a neighbor, who called me whilst taking the guest in. He gave her internet access (mine would pass into the courtyard too) but she did not contact me. I got a friend there, but her own partner had already returned. The reason of that urgency? She did not want to get her dog wet.
Since then, I have it in the full house terms / contract that guests are not allowed to call any craftsman for whatever urgency whitout my permission.
For the shared space, I have keys in a bistro, and with friends. Needed that three or four times since last Summer.
Maybe you will need a code lock on the bedroom door if people loose that key 😉
@Robin4, my notifications were switched back to default No Notifications, I only see your posts today. I love the opossom story plus joke. Have to tell that to my sister. Her first husband had an uncle who was a priest, whole family very holy. She is not (you should do a complete background check before falling in love, but she had not) When they had a big celebration of his 50 years jubilee as a catholic priest, my sister landed in a hospital, 50 miles over country roads, all sirens hurling. In the end it was no early heart attack at 25 years old but only a panick attack. - A bit of swinging of holy smoke and sprinkling of holy water does not only drive oppossums away. 😉
@Maryam-Al-Fakheer0, I get a lot of guests who choose a shared room to have some handholding in case of need, single women who lost a partner and fear to be alone, single men who want a female (motherly) presence in the house, young folk on their first trip. Those that are honest to themselves about it, or even tell me, are usually very grateful, also in reviews.
I get a few also who book cheap and hope for extras, but my place is not the absolutely cheapest. It is cheap for the service.
Maybe a private room is more attractive to people who do not want to pay a hotel, but want to get the service plus extras. A shared room is a different experience, so maybe the guest who want maximum benefits on minimum price hesitate at that.
But the most demanding guests, who think it is normal to can dispose of company and ressources without giving back a thing, still give bad star evaluation (not the written text)
