We loved our stay here! Great location for exploring Berlin, easy to get into the centre and great for exploring Kreuzberg and Neukölln. Quiet and residential. Very friendly staff who let us leave their bags with them after check out when we had to burn some time. Only thing I would say is the room was quite hot, so you might need to turn the radiators down (unusual in November).
Overall, great value for money! You won't regret staying here.
