This is a very interesting hotel, with fully automated check-in (no desk) and all electronic entry (via "keys" on a website or a touch pad combination lock). The rooms are brand-new and sleekly designed, and everything is comfortable and easy to use. It's in a great location, virtually on top of an S-Bahn station, with several great restaurants and a brewery pub nearby.
My only complaints with the room were the motion-sensitive light near the door, which triggered when I got up to use the bathroom during the night and didn't go off for several minutes afterward, and the HVAC, which ran loudly all night without seeming to do much actual cooling. But the room was nevertheless very comfortable and a great place to stay for a few nights.
