Henrik was a very helpful and welcoming host, we were earlier than expected but he was very accommodating and let us settle in before he finished sorting the room out.
The apartment was in an ideal location, 15 minutes walk from Alexanderplatz station or there's an underground around the corner, two stops from Alexanderplatz.
The apartment itself was very nice with some original features and although only a studio apartment the high ceilings make it feel very spacious.

We had a great stay and would definitely recommend.
