Great stay, always a pleasure. We have a long history in my family with this hotel, so it's always our choice for Berlin.
We stayed in a Junior Suite, and while the room was very comfortable, the beds were quite hard, to the point where we had to ask for extra duvets to lie on.
The hotel itself is old school luxury, but with updates. There's free wifi, there's a gym, there's even EV charging options (when they work). But the point of staying here is to enjoy an updated version of yester-year's version of luxury.
