The flat is compliant to the description, clean and well equipped. It is close to Alexanderplatz (direct bus line from Tegel airport) and has a great view over Berlin. Hae Ok is a very helpful guest. We had good communication before and during our stay. The only downside of the flat is the railway station just at the foot of the building, which is quite noisy. It could be a real problem for light sleepers as trains start to circulate around 4:00 am.
