Hi @Jihan35!
Your property is beautiful! Re increasing bookings - have you adjusted price to reflect seasonality? You could try to play around with your nightly rate to see if that generates additional bookings.
Additionally, you may want to consider swapping out your living room furniture for something more family friendly and comfy. While what you have is gorgeous, it doesn't scream "let's hang out in the living room with the kids and play games". Just a thought.
Good luck!
