Italian PhD student looking for an accomodation near to the univeristy

My name is Filippo Vaccaro and I am 25 years old. I am an Italian Phd student at Sapienza University of Rome. My subject is Medieval history. My research focuses on the Mediterranean Sea in Middle Ages and especially on the economic and social history of the Venetian society in Crete.
My hobbies are watching movies and listening to music. Also, I read a lot! I will be spending three months (from April 14th to the middle of July) in Heidelberg as an exchange related to my doctoral thesis. I have a big family in Rome and a stable relationship with a girlfriend.
I am a very precise person and I like to keep my stuff tidied up. I like working with kids; indeed I both help kids in studying Greek and Latin and volunteer in church in the first comunion and confirmation courses.
I hope to find a small accomadation in Heidelberg as soon as possible.
