1 room apartment Heidelberg close to neuenheim/Altstadt

My name is Gaia Scilironi, I am 24 and I come from Italy. In October I will start a PhD at the ZMBH in Biochemistry: I can definitely say that science is my passion. I also like running, traveling and hiking. I am studying German but it takes time, and that is why this message is in English. I am a clean tenant (I really hate dirty places) and I am quite tidy. I am not a party-person and I prefer to have small gatherings with friends, good food and movies in my free time. I don’t smoke and don’t have pets, but I like having plants and care them. I like living alone and have my own spaces. Thus, I think I will be a good tenant and the neighbors will not complain. I am looking for a studio/1 room apartment/small flat to live in during my PhD. I am already in Heidelberg since I am doing an Erasmus internship here, so I am available to meet you in person and see the houses.
