This is a WordPress plugin that generates responsive and styled maps, using the simplest shortcode!
After you install the plugin, no setup is needed, just go to the plugin’s admin and copy-paste the code from there.
The plugin allows multiple markers per map and multiple maps per page.
No API key required. 40 beautiful map styles are included.

Create a simple back&white map using just an address:
[res_map address="New York" style="2" icon="gray"]

Or create a map using just latitude, longitude like this:
[res_map address="40.6700, -73.9400" directionstext="view directions to here" icon="blue" style="38" description="<img src=''> {br} The address or phone number"]

This map plugin also works with tabs:
