This flat is very spacious and light.
Location is very central near to Kreuzberg and also to Mitte. But it is a bit of a weird spot which means you are not in either area. Have to take a decent walk or taxi to either.
The guys that run the flat are a little disorganised, but nice enough.
The apartment is a little run down, the furnishings are all very simple but cheap. There is no freezer.
Overall we were very happy with our stay.
