25 years old woman looking for accommodation in Piazza Bologna

I will be in Rome for 3 months between June 15th and September 20th this summer. I will do internship at Sapienza Faculty of Economics. I am a research assistant and the purpose of my travel is mostly research oriented. When in Rome, I consider studying during the weekdays, exploring the city during the weekends. I look for a single room in an apartment shared with some other students. A peaceful, clean and tidy place is a must for me. Proximity to the campus is a priority, and as long as it is within the walking distance I might pay more than my boundary price.
