Customizer Theme: How to align the map of google maps on my site

Good Morning.
I need help to align the map of google maps on my page https://armeriacastro.es/nuestras-tiendas/
As you can see appear a photograph from the front of the place, just below the contact details and just below the Google map .
What I would like is that instead of everything goes left-aligned, to better distribute the elements, I would like to occupy the entire width of the page. Could you tell me how I get this? thanks, I hope your answers .
