We had very good one night stay here. There were no suites available so they offered us comped mini bar (nice touch). Late check out at 4 pm was not a problem. Hotel has a lot of nice art that we liked. Location is great for getting to the airport < 1 h by train with one change. Breakfast was in the restaurant downstairs and was good. It also had free flowing sparkling wine. One problem, more so about Germany than the hotel, is that many people smoke here and you can smoke outside. They are also not very considerate and we were shown middle finger by one couple when we asked them to refrain from smoking b/c it's unpleasant for us. Oh well, the only public health campaign that worked in the US I guess. Note that one of the best restaurants in Berlin - Facil - is right around the corner. I highly recommend it for both lunch and dinner. Phenomenal food.
