This apartment is very quiet, large, well equipped and comfy. The two bedrooms are far apart so nicely private for sharing. There is a clothes washing machine but you have to air dry which for our needs was OK just note you have to plan your wash two days ahead. All furnishings are IKEA so practical but firm not luxe. What we enjoyed most was the perfect location which is real close to several foodie spots, transportation from one of the main hubs in Berlin and ten minutes walk to major retail shopping. We would absolutely stay here in future and totally recommend for three or seven people keeping in mind just one bathroom/toilet. TV in German only was only minor negative since we do not know the language. We got news from home via internet which worked very well.
One arrival note the very sweet caretaker who holds the keys DOES NOT live in the area so travel delays need communication which I felt badly that I did not make more of an effort to do and caused her inconvenience.
Overall a wonderful home away from home!
