Very stylish apartment, bold modern interior mixed with "Altbau" flair typical for Charlottenburg. Spotless clean. Great location. Friendly hosts.
We stayed there for a long weekend with our 2 kids. There is one double bed, one folding bed and the sofa, which is not a sofa bed, but a large leather sofa with a wool blanket.
There were a couple of minor issues, but overall a good experience!
