@Sophie446 your listing looks very nice!
Your photos are also good. There are a few tall photos (I think wide photos are preferred), but I don't think the photos are the problem.
When I searched in your specific neighborhood, your listing was on the first page, (#17 of 87), but that was with the map showing just very close nearby. There are a LOT of AirBnB listings in Tblisi it seems, so there is much competition.
Are there busy and slow seasons for travelers in Tblisi? I do not know the area, so I don't know if people like to travel there in the winter or summer or spring. Sometimes bookings are slow because there is not much travel to the whole city.
You have good reviews so far! You need more reviews so the stars appear.
It is very difficult to get started with a new listing, since you need reviews (but how do you get more guests without stars and reviews?)
Even though your price is already good, some hosts (just to get started) will offer special discounts so they can get more early guests because they really need the Stars and Reviews.
It is not that your listing is not worth more (it is!), but to overcome guests' reluctance to try an apartment with few reviews, hosts offer special incentives. Once you get going and have more reviews, then you can put your price back where it belongs.
