I would definitely say to discuss it with her, and discuss it every time you have friends come out. It is her apartment, too.

Four friends at once in an apartment where two people are already living could be a bit much, so I really wouldn't do that too often. But also, if every weekend someone different is staying there, that would also be tiring for your roommate, i'm sure.

If you wanted people to visit often, you probably should've thought about getting your own place.

Another solution is that if your four best friends are at home, and you're farther away, maybe since there's four of them and one of you, you should go home more than they should come visit you.

But then again, after college, people make all these plans to go visit each other all the time, etc. and after awhile, real life catches up with you and it becomes very hard to do with a lot of frequency!
