Apartment is modern and clean, we found that it was well situated between two metro stations. Unfortunately the shower flooded on the first day and water nearly left through the front door, when we told the front desk they simply gave us a mop which did not help due to the amount of water and did not solve the problem. When I went down again they said they would come up and they found the sealant wasn’t on the shower door.
We were told “not to have any parties” which was fine as we were visiting Berlin to sight see and when we got back each evening we were tired, however, the ‘security’ knocked on our door twice on separate nights for apparently being loud when we were just talking and not shouting/playing music. We were never told that there were security and felt unsafe knowing that a random man was knocking on our door (me and two other women).
