Have any of you rented a room out to help with expenses and/or for companionship? If so how did you go about it?

I have two extra rooms, and while I enjoy being alone during the day, at night I crave someone to talk to besides my dog. And I had the flu this week and those first couple of days when I felt like I was dying I couldn't help thinking - what if? It would be nice to know if I keeled over someone would call the ambulance.

I live in a pretty isolated place - and love it. But, if I found a person who I wouldn't drive crazy, and vice a versa I'd give it a try.

Thing is I have the house furnished, so I wouldn't want to have to find room for someone's furniture, outside their room. And what to do about cooking, groceries, cleaning up, etc. Would it be more complicated to be worth it?
