My brothers and I had a wonderful stay at Vincent's place.
It is exactly as you see on the pictures and is full equipped to have a super comfortable stay.
Heating system works really well, we appreciated it very much because January is very cold in Berlin.
Its location is, for sure, the best thing to talk about: close to the Metro station and in the very Center of Kreuzberg Neighbourhood, so there are several bars, restaurants and night life clubs that will make your stay absolutely enjoyable.
I do recommend the place and I am sure I will book it again if I visit Berlin in the future.
