Margarita, I'm so sorry that you have run into this issue. You have a beautiful property! Your host rating also demonstrates you are a great host for guests. Congrats!
It would be interesting to see your "Insights" tab to see the traffic your property is getting.
My recommendations (in order or priority):
1. Run a complete listing audit and optimization.
2. Lower the minimum nights in order to be seen on more searches. According to my market analysis, average stays throughout the year are always below 3 nights.
3. If all else fails, close this listing and relaunch again.
Would love to help more if you need it!
