Hi Adhina, what you are experiencing is common for a new host and listing. Airbnb do promote your ranking for the first month or so to get you underway but, sooner or later you have to swim in the big pool like the rest of us.
You have started off well with one great review and I am sure more will follow, and that breeds confidence in searching guests.....they want to see that you are competent and can be trusted. Many hosts are hesitant about taking on a guest with no reviews, and the same does apply with guests, they want to see a track record.
Success breeds success though Adhina, learn from each guest how to become just that bit better, and keep on trying to provide great experiences, and that trickle of future guests will turn into a steady stream just like it has for many of us.
All the best.
Cheers......Rob
