Ayse's colleague met us when we got to the apartment in the evening and went over everything. We were driving there and Ayse reserved a spot for us in the apartment parking lot.
There are plenty of restaurants nearby that are open late. The train station is at the corner and it is a short ride into Berlin. You can see the tv tower from the apartment. You can easily walk to the TV Tower and Alexanderplatz or take a 5 min underground train (Ubahn). You can walk from Alexanderplatz to the Brandenburg gate and Reichstag.
The apartment is very open and comfortable. It can accommodate 6 adults. We were only 2 adults and 1 child, so it was super nice to have the space. The kitchen and bathroom were clean and well-stocked.
We had a good experience and would highly recommend the place!
