As you can see in the above image, I looked for a hotel in Hiran Magri Area, Udaipur. And the sidebar displays a list of different hotels. Now, as you hover on any hotel name, it will pop the pin in Maps. Also, if you hover the mouse on any pin, it will the hotel name in the sidebar.
The sidebar shows all the hotels with their pricing, reviews, and ratings which will help you down to narrow your search. Also, you can compare different hotels in the sidebar by comparing their prices and reviews given by other customers.
