Hello @Vishnu42, you have a very nice and well-maintained property.
I will have some recommendations.
If you rent out rooms in your house, you need to create a separate listing for each room. In this case, each room will have its own calendar, and different rooms can be booked separately by different guests. You can also create another listing - for the whole house.
After that, you need to link the calendars of each room to the calendar of the whole house.

And one more advice - take professional photos (including daylight photos) of the rooms, house, territory and surroundings. Professional photos will look completely different and will show all the advantages of your property.
