Girlfriend is having a party at her apartment complex with friends and this includes guys?

So my girlfriend is having a party at her apartment complex not her actually apartment but it’s basically the little hangout room which is right outside her door. I am not invited to this which I really wouldn’t care about if their wasn’t guys showing up to this party and yes there is girls to. I let her hangout with her friend and have her time to herself and yes there sometimes is a guy with her and her friends which really doesn’t bother me because I trust her, but I’m just not comfortable with them coming to her apartment complex without me there. Should I tell her I’m not comfortable with this?
