I had a good stay at Anna's. Top advantages of the place are it's location, really close to wesserstrasse which is a lovely street with bars, cafes and small stores. Generally, this is one of my favourite spots in Nuekolln. Also, it had a great value for what you get. Anna nad her roomate were really nice. We didn't hang out that much but had our moments.
Some disadvantages are that 1) I found the hygene level in the place not too good. My room was clean and all, but the sink was full of dishes for a long time and so it wasn't so nice to use it. 2) the room I stayed in basically had only a be it, and because Anna crashed in the living room while I was there, I didn't really have anywhere in the house to lounge in. There's a small spot in the kitchen but other than that I had to sit on the bed.
All and all, it was a nice stay though and I would recommend the place. For the asked price, it was a great find.
