How can I deal with an inconsiderate house guest?

My former roommate often spends the night at my house (with boyfriend in tow) when she visits our town. Note: she is not visiting me, just staying with me while she flits about.

The problem is this: she is extremely messy, loud, and obnoxious as a house guest. She spreads her stuff all over the house (and she always brings an alarming amount of crap), cooks and then leaves the dirty dishes in the sink, and stomps across our wooden floor when she comes home at 2 am. Basically, she’s the houseguest from hell.

I could probably bite my tongue about this if it weren’t for the fact that I have two lovely roommates who also have to put up with this when she is here. And that’s not fair.

Last time my friend stayed here, I asked her beforehand to please be quiet when she came home and to try to keep things tidy. She was just as bad as ever.

How can she not realize what she is like?! I feel that it’s rude and disrespectful—am I being too sensitive, here?

Anyway, this has to stop, at least for my roommates’ sakes. Aside from asking my friend not to stay here anymore, do you have any suggestions? Or similar experiences (only because hearing those might make me feel less crazy)?
