The apartment is really nice and comfortable. Situated in a cool area (Kreuzberg), it's very close to every kind of restaurants and cafés. I stayed in this lovely flat 4 nights and I have to admit that it was beyond my expectations. First of all, despite being located in the basement, you don't even realize this. The bed is really comfortable, the shower is huge and the living room very stylish with a "lifted" sofa and a big TV (and an impressive DVDs' collection). The landlord has also drawn a personalized map of the local points of interest.
I really recommend this place!
