How to edit /accommodation/ in the link?

It is possible to edit the /accommodation/ slug in 2 ways:

Method #1

by editing translations of the plugin. This would let you change the default link:

https://your-site.com/accommodation/double-room

to

https://your-site.com/room/double-room

You may also edit the translation to change the following slugs of the Hotel Booking plugin:

/accommodation-category/

/accommodation-tag/

/accommodation-facility/ for Amenities

/service/

Note: After you edit translations for slugs you should navigate to Dashboard > Settings > Permalinks and Save changes to refresh the links.

Feel free to use the Loco Translate plugin to easily manage translations.

Method #2

by applying the codes below to the functions.php file of the theme:

Note: After you edit translations for slugs you should navigate to Dashboard > Settings > Permalinks and Save changes to refresh the links.

/accommodation/:

function theme_edit_slug_mphb_room_type( $args, $post_type ) {

        $args['rewrite']['slug'] = 'apartment';
    }
    return $args;
}

add_filter( 'register_post_type_args', 'theme_edit_slug_mphb_room_type', 10, 2 );

/accommodation-category/:

function theme_edit_slug_mphb_room_type_category( $args, $taxonomy ) {

    }

add_filter( 'register_taxonomy_args', 'theme_edit_slug_mphb_room_type_category', 20, 2 );

/accommodation-tag/:
