Had been at this place for Openstack Berlin conference at City Cube, in november. The place is fantastic, with superb connectivity. It is 3 mins away from S-Bahn station and 8 mins away from U-Bahn station. Citycube was only two stops away. There are a lot of restaurants in the neighborhood (lots of Indian if you are interested) and totally felt safe. Apartment was sparkling clean and tastefully done. Could not have asked for more!!
