Is it possible to style the map?

The Maps Premium View does allow you to add custom styles to change the look of the map.

The process is quite simple:

1. Access the styling wizard at https://mapstyle.withgoogle.com/

2. Customize the map to your liking using the settings on the left side panel. At the bottom of that panel, there's a "MORE OPTIONS" link containing even more detailed options.

3. Once you're done, click the blue "FINISH" button at the bottom of the left panel.

4. A dialogue will pop up with your new styling as a JSON-formatted snippet. Click the "COPY JSON" link to copy that code.

5. Paste your recently copied code snippet into the Custom Map Styles option in your View editor's View Settings metabox.

Update (or Publish) your View, and that's it! Check your Map View for the newly applied styles.
