Helpful staff, efficient check in and service.
The room was clean and huge even with 3 of us staying there. It is a quiet location but with good restaurants in the immediate area. The metro is just a 5 minute walk away.
The only negative thing I can think to say is that, as it was the middle of the summer, there was no air-con. But this was only a minor gripe as they provide a large fan in the room.
A personal highlight was being able to an early morning run from Charlottenburg into Berlin and back.
Highly recommended, would stay here again!
