push @{ $no_name_found { $user_name } }, $city;
The value associated with the key is an
array reference, and so
my $value = $result->{$key};
print "User Name = $key - City: $value\n";
will output something that looks like
User Name = User - City: ARRAY(0x3eafa1c)
You might get something closer to what you expect with
my $value = $result->{$key};
local $" = ', ';
print "User Name = $key - City: @$value\n";
or
my $value = $result->{$key};
print "User Name = $key - City: ", join(', ', @$value), "\n";
or something similar.
