@Poorna-Jay-Madhav0 Your listing is beautiful and so is the area in which it sits. It appears very clean, well maintained and completely ready for your guests.
My comments probably are my own tastes, but here they are.
The Living room looks nice, but it might be a little more friendly if you put a little something on the shelves by the TV. Those bare shelves look foreboding to me.
The glasses at the far end of the Dining table look cloudy. It is probably the sunlight, but I would either figure out a way to make them look as nice as the front glasses or eliminate them altogether.
In the Half bathroom, maybe add a vase with artificial, but very realistic silk flowers. Perhaps add a colorful hand towel as well or leave it white, but with an emblem or some other color showing. It looks rather stark and sterile. This will help soften the look.
The $250.00 per night seems reasonable. The cleaning fee to me is quite high, but then again, I do not charge a cleaning fee. Maybe offer FREE cleaning fee through September with a 3 night stay or something like that and test the waters to see if that could be the problem.
Others may not agree, but there you go. I think it is quite lovely and have no idea why you are not getting bookings.
