The flat was as described. It was clean and modern. There were a few minor issues we had. As clearly stated in the description, there are a lot of stairs to get to it (102 to be precise) which wasn't much fun with heavy luggage and at the end of a long day of exploring. What I assume was the hot water storage was constantly refilling which was clearly audible throughout the night which made sleeping a little difficult. Also the shower pressure wasn't very strong. As I said though, these were not huge issues and overall it is a nice space to stay in and we enjoyed our time in Berlin very much.
