The hotel bills itself as a "contactless" hotel, although this is not easy to see on the Expedia website. To get in, whether to the hotel or to one's room (or indeed, even to know which room one is assigned), one needs a code. This code is apparently supposed to be sent by email. I, however, never received it (not even in spam). And when I tried to call the number provided in my booking confirmation as many as 20 times, I couldn't get through; I got cut off each time (not that there was anything wrong with my phone). When I found an alternative number, I was unhelpfully told that sometimes when one books through a site such as Expedia (as opposed to through the hotel's own website, which I never would have found on its own), the code sometimes doesn't come through. Thanks a lot! Fortunately, after about 1/2 an hour, a cleaning person opened the door and let me in. But imagine if it had been raining? Or if it had been the middle of the night? And when I complained, I was told that I should just have "relaxed" (ausatmen, literally, to take a deep breath and breath out). If you arrived after a transatlantic journey--exhausted and wanting nothing more than a shower--and found yourself unable to get into your hotel and with no one there to help, would you just relax? And I speak German! By way of apology, such as it was, the hotel said that they would have offered me a free breakfast (how generous!) but, given that I'd already complained on-line, they wouldn't!
