The idea behind the new tool is to showcase specific areas of a destination so users can find restaurants, attractions and accommodation at a more granular level, including their respective reviews.
Neighbourhoods is a mobile-based product (including on both the Android and iPhone apps) and allows users to locate their destination in a particular area of a city and immediately get information about that neighbourhood.
This works the other way round, showing on an existing listing for a product which neighbourhood the service is in.
