As I do not live in Tel Aviv, I do not know the pricing market as well as you would. However, I have visited and stayed there before. It was for work and I stayed at a very high end hotel for about half the price of what you are listed at. I thinking perhaps it could be your pricing is the lack of inquiry. My other thought would be to see how you can add sleeping arrangements for a couple more people. As you can sleep 4, a hotel room can also often sleep 4. If you are able to sleep a couple more people, it would set you apart from the hotel market and give you an edge to that competition.
