Great location! Can walk to the train in 5 minutes and easily walk to Brandenburg gate, Reichstag... through a beautiful park in maybe 30 mins. Great restaurants are nearby as well, especially on the other side of the river (I recommend Walhalla for breakfast and German food at good prices as well as an authentic Indonesian place a little further). The place is simple but spacious with everything you need. Best of all, it has a Yamaha upright piano which, albeit out of tune, is very nice to play.
