In short :CONSIDER OTHER OPTIONS BEFORE COME TO THIS PLACE
In longer:
Positives first : :) There is a lake near by (you can't see it from the balcony). You can park your car in front of the house for free.
In the corner there is a great kebab place, I really recommend it.
The negatives :
This place and this owner felt like a scam.
All rooms was very very dirty. Had to wash and clean everything before use. It was a priority for us to stay in a no smoking flat,because of health issues. But the whole place smelled like cigarette ash. All of our clothes got bad smell, we bought numerous of air freshener to maybe solve this problem. Also had to buy and the pills to not get asthmatic attacks. The owner only said about this situation :"very strange, we don't allow smoking inside" but other than that nothing happened.
We just found the keys in a secret place. And put them back when we left. Never met with anyone. The owner is some kind of company with 10+ apartments.
We had problems with the internet connection and quality. I worked remote or tried to work for this place. Talked with the owner numerous times, but we never got any solutions. Had like a day response between answers, said the he/she gonna answer today but never got an answer, only send us something else a week later.
As I mentioned before we had problems with the smoke smell, also had asthmatic problems from it. Talked with the owner, but they show no signs of cooperation. Also before we moved in, I said I need a good quality internet because I was working remote,but noting happened. All I got after 3 weeks is a restart code for the router, but that was never solved the problem.
About the area :
If you want to get to Mitte (Berlin center) you have to change trains in Gesundbrunnen which was a dangerous place even in daytime. We only lived 5 weeks in the apartment and had trouble there. Also there were some shady people in the corner of the house's street. For a single girl I won't really suggest walking alone.
