Filtering more than one term in a taxonomy in WP

You can use tax_query and use the AND condition:
Reference: WP_Query under Taxonomy Parameters

$args = array(
    'post_type' => 'post',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'hotels',
            'field' => 'slug',
            'terms' => array( '1 Star' )
        ),
        array(
            'taxonomy' => 'location',
            'field' => 'slug',
            'terms' => array( 'loc1' )
        )
    )
);
$query = new WP_Query( $args );
