woman (25) looking for a room/apartment from May to August

Hey! I'm Ekaterina or Kat for short, a 25 year old English teacher, translator, artist, and content creator from Moscow looking for a place to stay from 01/05/2022 to 15/07/2022. I will be visiting Berlin to take German language courses and learn the culture :)

A small apartment would be ideal, but I'm considering rooms as well.
All I really need is a bed/mattress and a desk to work on. I would like to stream on my computer sometimes, so a good quality internet (50 mbps and higher) is preferred.

My classes are scheduled for early mornings til afternoon, so I will mostly be out at DID during the day and quietly doing my homework in the evening.
I also stream drawing and video games sometimes, but I have a lot of respect for other people and will not be noisy during nighttime. I like my environment clean and tidy, so I think I would be a pleasant roommate/neighbour :)
I speak fluent English and Russian and know a tiny bit of German but hopefully can improve soon!

If you have any questions please don't hesitate to ask! I have a scan/photo of my ID and bank statement prepared.
