unordered_map of different custom types

Suppose if I have these two enums:

enum Type
{
    Type1,
    Type2
};

enum Location
{
    Location1,
    Location2,
    Location3
};

Now I would like to have a container that I can reference like container[Type1][Location1] = 5;

I don't need the elements to be sorted but I need to be able to have duplicates like container[Type1] can be either Location1 or Location2 etc.

I was thinking to use an unordered_multimap<pair<Type, Location>, unsigned int>> which kind of provides what I want, but does not allow me to access the elements as described (or at least I don't know how to do that)

What suggestions do you have?

I believe you're looking for nested maps:

std::unordered_map<Type, std::unordered_map<Location, unsigned int>>
