Looking for a single room in Ames, IA

Hi everyone, I'm a second-year master's student in agronomy at Iowa State and I'm looking for my own room in Ames. My current place is getting sold, so I've got to be out soon. - Private room - Budget: $500/mo - Close to campus or on a CyRide route - Long term preferred, I'm here for at least another year I'm 29, a bit older than most grad students, pretty quiet and spend a lot of time out at the research farms. I cook, I clean up after myself and I don't have pets. Thanks for looking!
