This building is not located in an area where you have everything at your doorstep, but everything is easily accessible by a ~10 minute walk. The building felt a bit old and uncared for, but the apartment itself was just fine--not breathtaking but plenty spacious and well-equipped. Contacting Kemal and Ferat was quick and efficient, which I appreciate very much. We were satisfied but will probably explore other options on our next trip to Berlin.
