I'm french and I have been living in the states for 2 years now.
I would describe myself as an easy going guy, laid back and friendly. I get along well with anybody and I'm pretty open minded.
I have been living in different shared houses / apartments for 5 years now. In the day to day life with me: I dont pay attention to minor points but try to be up to date on bigger one (rent, bills, etc ... ;-) ). Even if organising a party at home is never an issue for me, I 'm pretty respectful of my roomates and would never do anything without general agreement. On the other side, a good diner and a movie is also a great night to share with friends/ roomates.
I think I would be a better guest than a host ;)
