If they do something you don't like tell them to stop or leave. Get a thicker skin. If they keep coming over make them do work. "Mom, so nice of you to drop by. Here's a mop. Wash the kitchen floor for me. I'll be back in a half hour."
You don't understand what it's like to have overbearing parents. You feel guilty because you know they love you and are trying to "be there" for you, but you also don't like their approach, and they make you feel guilty about it. It's not a matter of how YOU act but how they treat you. No matter how you act, they are likely to see it as a case of you being immature and needing their help -- whether you stand up to them (you're being immature by "acting out") or let them treat you like a child (you obviously "need" to be treated this way).
OP, I feel for you. I would make it very clear to them that you aren't comfortable with the idea of them getting an apartment and visiting this often. Go talk with a therapist if you need help confronting them on this. I know it will not be easy. But you need to be upfront and tell them ahead of time that you aren't comfortable with this decision. Tell them that they should consult with you before making such a big decision, especially since it seems like their assumption is that they are expecting you to spend most of the week they are in town with them every single month.
Tell them that you want them to be in your lives but that you're very busy and that you think it would work out better if you continued to see them according to your original arrangements. Say you think it would be tough on the kids to have them there so often and then leave again or something -- if you feel like you want to use an excuse like this.
If they go ahead with it anyway, make it clear that you do not support this and that you cannot guarantee that you will be available during that week each month. They need to know that you will not drop everything to spend a week with them every month. Perhaps you'll have to travel for work that week, or the kids will have after-school activities or camp or whatever.
Set serious boundaries and stick with them if they do move here. They need to call and arrange with you ahead of time for get-togethers. They cannot drop by unannounced. They will not get a key. Maybe make some specific things for them to do -- like pick up your kids from school/daycare that week or something.
