29 year old woman looking for accommodation in Berlin

I was born and raised in Gaborone, Botswana which is located in the southern part of Africa. When you first meet me, I tend to lean more into being shy, however, my friends would describe me as observant, talkative, outgoing and independent. In my free time, I like to explore the city, try out different restaurants, find hidden gems. On weekends, you can find me with my friends having a glass of wine at home or going window shopping at the mall. I am somewhat of a night owl, but I do try to sleep at 10 pm and wake up around 8am during the week. However, due to my class schedule I have an 8 am class on Friday, so I would be up by atleast 6am of Fridays. On weekends I sleep around 12midnight and up around 10am. 

I am a pretty social person, but also love my alone time. I want my house/apartment to be a place I can have people over, but not a place thats constantly full of people. I do not mind roommates hosting small parties - as long as it is communicated well in time. I am down to get to know each other as we will be staying together after all - the occassional watching TV together, hosting a games night with our friends or simply sharing a meal together every once in a while.

I like to keep common living spaces clean. I do my dishes after eating (unless I am late) and put them away every night. I am open to the idea of a cleaning schedule to keep things organized.

My monthly budget is 350euro and I am looking to move in between January 15 to January 31. I am hoping to find a house near Karl-Marx-Straße or within a 50km radius of the street. I would like my own bedroom and I am open to living with 1-3 other people. 

Here are some quirks and relevant information: I cant stand dirty bathrooms and people getting into my room without asking first. So, if you are someone who does not clean the bathroom after taking a shower, we might not be a good fit. I am not a smoker and I do not want to live with smokers.
