Everything was as expected. The apartment was clean and tidy, the location was in a nice neighborhood within walking distance to lots of bars and restaurants, small stores... The metro was close and just 3 metro stops from the very city center (Alexanderplatz) and not so far from the East side gallery (one of the pieces of the Berlin wall).
We didn't meet Igor but we didn't have any issue for picking up the keys or any other thing. Overall, great deal!
