Have stayed and cannot recommend the hotel.
The room they gave me (as globalist) is tiny, 17 or 18 square meters (190 square feet).
And it is badly designed. There is no chair (well, there are two small stools as night stands, but you could hardly put them anywhere else as there is no space).
There is no room to place a standard size Rimowa cabin trolley. There is something to the side of the bed with triple functionality: Luggage rack, minibar, in-room safe but it only fits a cabin trolley closed. When you fully open the drawer with the safe, you can fit it - see pic - but lose access to Minibar (one soda, two bottles of water) and the safe.
The desk is so tiny you can not properly put a laptop on it (it is too shallow to extend the monitor beyond an angle of 90°). Besides, it was already crammed with a water cooker, a vintage miniature car, and a caricature pic of Ronald Reagan, which I barely could fit on a shelf above the desk. The shower is brand-new but defective. The glass door is too large, with the isolation on the one end, it sits so tightly that I seriously feared breaking it as I had to use so much force to get it to open.
The design of room and public areas is what you'd expect from such a Moxy-like brand.
I do not what jobs you guys have but I could not have calls in the social working area downstairs--it is small, right next to the bar and reception, music is playing etc.
Breakfast was fine. Will not book again. I suppose if you party for 15 hours at Berghain and/or Kater Blau and just use the room to crash for 8 hours, it might work.
Oh, and there was a fire alarm at 6 AM in the morning.

My room had view of the trash cans but also the Spree...
Edit: Oh, and the room has no place to put cloth hangers. But the placed a few of them on the floor (I kid you not) anyhow.
For Hyatt in Berlin, I recommend the GH or, at a lower price point, the Sly (Mr and Mrs Smith).
Edit2: This used to be an ibis and it seems the didn't want to reduce the room count.
