Unbelievably unfriendly security lady at the reception. I had to leave the hotel in tears because she made me ready in front of the guests, in front of our 3 children. Even the service at the bar probably got the incident. My husband and our 3 children (2,4,7 years) were in transit in Berlin. Actually we wanted to drink coffee in the lobby and of course the great aquarium show the children. We were also allowed in, the security lady let us in. After we finished with coffee and ice, my 4 year old son wanted to ride the elevator with me. I did not think bad and got the elevator. Promt other guests have joined. Only when we were in, I realized that I do not come up without a hotel card, you have to plug in the entrance, not at all. But then we started already. I asked the guests in the elevator if I could go down without a map and if there is a staircase. On my luck I pressed the EC button and on arrival on the ground floor was already waiting for me the security lady. It was immediately clear to me that there is trouble right now. I immediately apologized and told her that it only became clear to me in the elevator how it works with startup. She did not react at all. She told me that I had sneaked into the elevator according to her surveillance camera and endangered the safety of the guests. Her announcements were literally: her the lady, follow me (also not please), child at hand! With command tone par excellence! (my son was with me all the time). At the announcement: child to the hand! I was still confused, of course, followed her and said friendly, that I take care of my child already. My husband saw the situation from afar and hurried to it immediately. The security lady then informed us that the hotel was exclusively for hotel guests and that they only tolerated us because of our children (!) And that they also do not have to be friendly! On top of that came the reproach to my husband that he had moved away from our children for more than 20 meters! ?? I beg your pardon? What else should he have done? He came to my rescue, it's clear. Unbelievable, impossible, unfriendly, loud, almost threatening. I will definitely not go there, even from the feeling that I do not welcome there as a guest, but be tolerated
