I was lucky. I had to travel to Berlin on these dates and didn't realize if there was a Berlin Marathon on the same date. All hotels near the train station were fully booked, and miraculously, I got this corner room with a two-window view, including the TV tower. I can see the hotel is one of the historical buildings (saw the picture in the DDR museum 😁), though it was refurbished well. The breakfast area was packed with all the runners, but just enjoy the moment :) I will definitely come back to Park Inn if I have the chance to visit Berlin again.
