Even if the hotel could be fantastic, it was not the case for me. Hairs on the floor in the bathroom, seal missing in the shower and therefore water leaking on the floor after each shower, no coffee in the room (forgotten during cleaning...), welcome at reception was quite cold, couldnt get the room as i was 30 minutes early, matress was not soft and i could feel hard part of the matress, tv screen was so dark that it was not possible to warch it. These are little things, the worst is the noise all night long. Couldnt figure out where it was coming from, i had to call reception at midnight and no change after all effort from the security guy. I gave up and bought ear plug for the following nights.
A real pity as the room is huge, it could have been the best stay of my 10 days trip in germany.
The lobby and bar are amazing.
Personnel at reception the other days were nice.
