@Sylvia-Nazma0 Take advantage of the new ability in Airbnb to look at the prices of booked and unbooked similar places in London. Only you can determine if your place is worth more or less than each property.
Did you happen to have a look at Mike's suggestion and try out the Price comparison tool?
You can explore more information about it here : New pricing tool compares similar listings nearby . If you are already using it, I am curious to know if you made any changes to pricing strategy based on it.
