This is a peaceful and comfortable place to stay in Berlin. It's right by Checkpoint Charlie and other notable landmarks, but still very peaceful and quiet. It was a cool experience to walk by the checkpoint nearly every day. The flat is comfortable and bigger than expected with a lot of kitchen essentials (good for a long stay!), and a nice big bath tub to relax in after a day spent wandering. I could focus and do work, and I enjoyed going for runs by Landwehrkanal. A bit further from clubs and the hip scene, but transportation is so easy in Berlin we did not mind at all. Definitely recommend!
