We very much enjoyed our stay at John's flat in Charlottenburg. The location was great, a short walk to many restaurants and cafes, some of the best restaurants in Berlin where a few minutes away by taxi also. John recommended to us Insomne cafe which was next door to the flat, this cafe had wonderful breakfast and light meal options along with the best fresh ground/brewed coffee that I tried in Berlin. The S-Bahn station was a 5 minute walk, very convenient. The flat was clean and modern with comfortable foam mattress beds. My only suggestions to John would be to fix the shower tub drain which was slow, also to provide as others have also suggested more toilet paper. Other than these issues everything was great and I'd highly recommend a stay here. John responds very quickly to messages, impressive! Thanks so much John!
