Whenever you add property to Vayoo, an area of 2 km radius is defined around it.(*)
Your listing will be automatically compared with the properties located within this area and having the same number of bedrooms.
You can change your area's radius and number of bedrooms in the Settings button, which is on the top right corner of your listing's picture.
(*) If there are not enough properties within this radius, the area will have a longer radius, until enough properties exist within the area.
