International master student from Slovenia looking for a single room apartment for long term (at least 1 year)

My name is Živa and I am a 23 years old (female) student from Ljubljana Slovenia. In October I am starting my Master studies in Molecular Biosciences with major in Cancer Biology here in Heidelberg, therefore I am looking for a long term place to stay somewhere nearby.

Ideally, the place would be at least partly furnished (however, I would also consider unfurnished apartments if they would be located really close to DFKZ) with a decent kitchen and private bathroom. The max rent should be around 500 euro (including all costs).

I am orderly, communicative, non-smoker. I like sports (especially running and hiking) and being creative (I make Slovenian bobbin lace jewelry and sew backpacks, bags etc..). I am an active scout member and I love nature and traveling.

I speak English fluently and I also know some German since I was learning it in high school and I am eager to learn more. I have already lived abroad in a single room apartment so I am used of cleaning and taking care of the apartment on a regular basis.
