This is a very nice and cozy place in Friedenau. You have everything, the creaky stairs and floors, the high ceilings, a view over the city lights and one over the courtyard from the kitchen.
The bed is also very comfy and large and wifi is fast and works well. Everything you need when you work while travelling.
I also liked the shopping in Friedenau and it is just a short walk to even more shops in Steglitz - if like me you live in the middle of nowhere, it's perfect because you don't have to take the tram into Mitte (if you're too lazy or like me, managed to sprain your ankle).
