I was organizing an excursion to Berlin for 22 people and did an extensive search before choosing this hotel and I can honestly say that it delivers. The price level was extremely good compared to other hotels in the same neighborhood.
The location was really convenient: it was right next to Ku’Damm and close to U-bahn so travelling was fast and easy. The only problem I had with the location was a lack of night food (though the rooms have fridges and there is a convenience store nearby).
The staff was really helpful during the whole stay. As a highlight: One night when we were coming from a night club and asked about night food stalls nearby, the front desk personnel tried to search a place for us and when he couldn't find any, he offered to make us breakfast before the actual breakfast time.
The rooms were modern, a bit futuristic and I actually really liked them.
Breakfast was quite basic in Central European standards.
