Response is having value as a different property for each letter

I am trying to get a respose from node js. The call is made and in browser network i get correct response but when promise is resolved i get weird output.

to fetch in nodejs file

app.get('/hotel/hotelsList', function(req, res) {
     res.send('hello world');
});

service call

angular.module('hotelApp.controller')
    .controller('searchHotelCtrl', function($scope, $state, hotelService) {

    $scope.$state = $state;
    $scope.hi = 'hel';

    function success(response) {
        console.log(response);
    };

    $scope.hotelDetails = function() { 


        hotelService.fetchHotels('INDIA').then(success);


    };

});

resource factory

$resource(url, params, {
                get: {
                    method: 'get',
                    url: url
                }
            });

call to fetch hotels

function fetchHotels(country) {
            var fetchHotels = resourceFactory(basePath+ '/hotelsList', {
                params: {
                    country: country
                }
            });

            retu fetchHotels.get().$promise;
        }

Response is printed as

m {0: "h", 1: "e", 2: "l", 3: "l", 4: "o", 5: " ", 6: "w", 7: "o", 8: "r", 9: "l", 10: "d", $promise: d, $resolved: true}

Why is my response doesn't come as 'hello world' only ?
