This apartment was great for our group of 4 (3 adults + 1 teenager). Convenient location between U bahn and S bahn stations and numerous bus lines, several good restaurants (Petite Europe, Doener place, even a great Korean restaurant called “Wa Wa”) and grocery stores, all within an easy walking distance. The place was spot clean and spacious for 4 people. We got the check-in information by email the night before. You get a 6 digit code that you need to put into the keypad before turning the knob to open it. We had some trouble to use the knob because it was loose, but Nina sent someone to fix it next morning, The trick is to pull the door toward you (almost yank it toward you) before you turn the knob to the left to push the door open. The neighborhood is residential and generally quiet at night, but if someone walks by talking loudly, you will hear it clearly because the apartment is facing the street directly with large windows. But, for us, this wasn’t too bothersome. It is probably difficult to find a quieter apartment in Berlin, that has all the conveniences I listed above. I had to communicate with Nina a few times during our stay and she was very responsive. Overall, it was an excellent value, and we were very happy with the apartment!
