Place Autocomplete Hotel Search

Stay organized with collections Save and categorize content based on your preferences.


This example creates a map with a search box that finds all of the hotels in a specified place within a given country. The map then displays markers for all of the hotels returned, with on-click details for each hotel.

// This example uses the autocomplete feature of the Google Places API.
// It allows the user to find all hotels in a given place, within a given

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
