You have to aim for consistent 5 star reviews. The best way to do that is to provide your guests with an amazing stay and consider providing some extras like a snack basket- early check in when you can, passed to a local attraction. Be communicative and consistent. Train your housekeeper to a standard of excellence.
Did you delete some lower ranking listings @Luli18 I ask because your profile shows a 4.71 rating with over 200 reviews but the only listing attached to your profile is 4.96 with 91 reviews .
Even if you delete lower ranking listings the scores and reviews will stay on your profile .
