The accommodation is nice and neat. Basic furniture, cutlery and kitchen tools, nothing fancy, but everything you need. It is more of a hostel with an international touch in between Neukölln and famous Kreuzberg. So the location is just brilliant; the subway's not very far away.
On the contra list though is the fact, that the three of us only got one key to the room and apartment. Nothing too bad, but it still made things a bit complicated, as each of us did want to have some time in Berlin on their own.
After all, I can recommend this offer if you are looking for something basic to stay in Berlin.
