Craigslist Ad: Renting Out My Bathroom

"I am a female in my mid 60's and I am looking for a room mate. Times are tight and I need some extra money. I am willing to rent out my bathroom in my 1 bedroom east village home. My bathroom is large. You can easily put a twin air mattress in there. I only ask that when I need to use the bathroom, you or your air mattress are not in it. I do ask that when you are in the apartment, you confine yourself to the bathroom. I do not feel comfortable with a stranger walking around my living room. This might change as I get to know you better."
