Data Science student looking for an apartment (from 01.07. +/-)

My name is Gargi, I am 27 years old and originally come from India. To be able to study data science in Berlin I need an apartment from July on for 5 months. After that, I'm planning to stay in Berlin to work and live there, so I'm looking for a place that I can make my home for a longer time. Preferable is a clean, bright, and uncluttered apartment with furniture.
There are no pets coming with me, and I am a fairly quiet person who values a quiet, clean and organized surrounding. Having lived here for some time, I am very familiar with the German way of life and quite comfortable with it. I understand the everyday rules and courtesies one follows here.
My German language skills are not very good yet, as I have been very focused on my studies. However, I plan on joining German classes after moving to Berlin.
